Example Questions

Example Question #7 : Geometry

In which quadrant is the point \dpi{100} (5,-6) located in? 

Possible Answers:

\dpi{100} IV

\dpi{100} II

\dpi{100} III

\dpi{100} I

Correct answer:

\dpi{100} IV

Explanation:

From the origin \dpi{100} (5,-6) is to the right 5 and down 6 making it in quadrant IV.

Example Question #1 : How To Find The Points On A Coordinate Plane

Angela plotted points A through E on the coordinate plane shown below.

 

Points_grid

What are the coordinates for point B?

Possible Answers:

(7, 2)

(8, 8)

(2, 7)

(8, 2)

(2, 8)

Correct answer:

(2, 8)

Explanation:

Begin at point (0, 0) in the bottom left hand corner of the coordinate plane. From there, count the number of spaces you move to the right to line up with Point B. This will be the first number in the ordered pair. Next, count the number of spaces to move up until you reach Point B. This will be the second number in your ordered pair.  

 

You should have counted 2 spaces to the right and 8 spaces up. The ordered pair for Point B is (2, 8).

Example Question #2 : How To Find The Points On A Coordinate Plane

Angela plotted points A through E on the coordinate plane shown below.

 

Points_grid

What are the coordinates for Point A?

Possible Answers:

(6, 0)

(0, 6)

(0, 5)

(6, 1)

(1, 6)

Correct answer:

(0, 6)

Explanation:

Begin at point (0, 0) in the bottom left hand corner of the coordinate plane. From there, count the number of spaces you move to the right to line up with Point A. This will be the first number in the ordered pair. Next, count the number of spaces to move up until you reach Point A. This will be the second number in your ordered pair.  

You should have counted 0 spaces to the right and 6 spaces up. The ordered pair for Point B is (0, 6).

 

 

Example Question #3 : How To Find The Points On A Coordinate Plane

Angela plotted points A through E on the coordinate plane shown below.

 

Points_grid

Which point is located at the ordered pair (6, 7)?

Possible Answers:

Point A

Point C

Point B

Point E

Point D

Correct answer:

Point C

Explanation:

Start at point (0, 0) in the bottom, left corner of the the coordinate plane. From there, count right 6 spaces. This is the first number in the given ordered pair. From that point, count up 7 spaces. This is the second number in the given ordered pair.

 

By moving right 6 and up 7, you should have found Point C.

Example Question #4 : How To Find The Points On A Coordinate Plane

Angela plotted points A through E on the coordinate plane shown below.

 

Points_grid

Which point is located at the ordered pair (2, 8)?

 

 
Possible Answers:

Point C

Point E

Point B

Point A

Point D

Correct answer:

Point B

Explanation:

Start at point (0, 0) in the bottom, left corner of the the coordinate plane. From there, count right 2 spaces. This is the first number in the given ordered pair. From that point, count up 8 spaces. This is the second number in the given ordered pair.

By moving right 2 and up 8, you should have found Point B.
