How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: What are the coordinates of the point that is $3$ units right of the origin and on the $x$-axis?

Answer: $(3, 0)$. Points on the $x$-axis have $y=0$, and right of the origin means a positive $x$-coordinate.

Flashcard 2: What does the first number in an ordered pair $(x, y)$ represent on a grid?

Answer: $x$-coordinate (horizontal position). The first number indicates the horizontal distance from the origin along the $x$-axis.

Flashcard 3: What are the coordinates of a point that is $1$ unit right and $8$ units down from the origin?

Answer: $(1, -8)$. Moving right from the origin gives a positive $x$-coordinate, and down gives a negative $y$-coordinate.

Flashcard 4: Which ordered pair has the same location as "$2$ units left and $5$ units up"?

Answer: $(-2, 5)$. Left movement corresponds to a negative $x$-value, and up corresponds to a positive $y$-value from the origin.

Flashcard 5: What is the coordinate of any point located on the $x$-axis (in terms of $y$)?

Answer: $y = 0$. Any point on the $x$-axis has no vertical displacement from the origin, so its $y$-coordinate is zero.

Flashcard 6: Which direction does the $y$-coordinate increase on a standard coordinate grid?

Answer: Upward. Positive $y$-values increase as you move upward from the origin along the $y$-axis.

Flashcard 7: Identify the point with $x = -3$ and $y = 6$ as an ordered pair.

Answer: $(-3, 6)$. The ordered pair is formed by placing the given $x$-value first and $y$-value second.

Flashcard 8: Find the missing coordinate: If a point is $(8, y)$ on the $x$-axis, what is $y$?

Answer: $0$. Points on the $x$-axis require the $y$-coordinate to be zero regardless of the $x$-value.

Flashcard 9: Identify the point with $x = 10$ and $y = -2$ as an ordered pair.

Answer: $(10, -2)$. The ordered pair is formed by placing the given $x$-value first and $y$-value second.

Flashcard 10: What is the name of the point where the $x$-axis and $y$-axis intersect?

Answer: The origin, $(0, 0)$. The axes intersect at the reference point called the origin, where both coordinates are zero.

Flashcard 11: What is the name of the vertical axis on a coordinate grid?

Answer: $y$-axis. The vertical axis runs up and down and is labeled as the $y$-axis in a coordinate plane.

Flashcard 12: What are the coordinates of a point that is $4$ units right and $3$ units up from the origin?

Answer: $(4, 3)$. Moving right from the origin gives a positive $x$-coordinate, and up gives a positive $y$-coordinate.

Flashcard 13: Find the missing coordinate: If a point is $(x, -5)$ on the $y$-axis, what is $x$?

Answer: $0$. Points on the $y$-axis require the $x$-coordinate to be zero regardless of the $y$-value.

Flashcard 14: What does the second number in an ordered pair $(x, y)$ represent on a grid?

Answer: $y$-coordinate (vertical position). The second number indicates the vertical distance from the origin along the $y$-axis.

Flashcard 15: Which ordered pair has the same location as "$7$ units right and $1$ unit down"?

Answer: $(7, -1)$. Right movement corresponds to a positive $x$-value, and down corresponds to a negative $y$-value from the origin.

Flashcard 16: Identify the coordinates of a point on the $y$-axis that is $9$ units above the origin.

Answer: $(0, 9)$. Points on the $y$-axis have $x=0$, and above the origin means a positive $y$-coordinate.

Flashcard 17: What are the coordinates of a point that is $5$ units left and $7$ units down from the origin?

Answer: $(-5, -7)$. Moving left from the origin gives a negative $x$-coordinate, and down gives a negative $y$-coordinate.

Flashcard 18: What is the name of the horizontal axis on a coordinate grid?

Answer: $x$-axis. The horizontal axis runs left to right and is labeled as the $x$-axis in a coordinate plane.

Flashcard 19: Identify the coordinates of a point on the $x$-axis that is $12$ units left of the origin.

Answer: $(-12, 0)$. Points on the $x$-axis have $y=0$, and left of the origin means a negative $x$-coordinate.

Flashcard 20: What is the coordinate of any point located on the $y$-axis (in terms of $x$)?

Answer: $x = 0$. Any point on the $y$-axis has no horizontal displacement from the origin, so its $x$-coordinate is zero.

Flashcard 21: Which direction does the $x$-coordinate increase on a standard coordinate grid?

Answer: To the right. Positive $x$-values increase as you move rightward from the origin along the $x$-axis.

Flashcard 22: What are the coordinates of the point that is $4$ units below the origin and on the $y$-axis?

Answer: $(0, -4)$. Points on the $y$-axis have $x=0$, and below the origin means a negative $y$-coordinate.

Flashcard 23: Find and correct the ordered pair if a student wrote $(y, x)$ instead of $(x, y)$ for $x = 2$, $y = -9$.

Answer: Correct ordered pair: $(2, -9)$. The standard ordered pair format requires $x$ first and $y$ second, so reversing the student's $(y, x)$ gives the correct pair.

Flashcard 24: What is the ordered pair format used to name a point on a coordinate grid?

Answer: $(x, y)$. The ordered pair format specifies a point's position with the horizontal coordinate first and the vertical coordinate second on the grid.

Flashcard 25: What are the coordinates of a point that is $6$ units left and $2$ units up from the origin?

Answer: $(-6, 2)$. Moving left from the origin gives a negative $x$-coordinate, and up gives a positive $y$-coordinate.
