Example Question #3301 : Algebra 1

Which ordered pair is plotted on the following graph

Coordinate plane 2

Possible Answers:

Correct answer:

Explanation:

An ordered pair can be looked at like this:

(x-coordinate, y-coordinate)

where the first number represents the x-coordinate and the second number represent the y-coordinate.  

The x-coordinate is simply the position on the x-axis.  The y-coordinate is the position on the y-axis.

 

If we look at a coordinate plane, we can see where the x- and the y-axes are located.

Blank coordinate plane

The x-axis is horizontal (going left to right) and the y-axis is vertical (going up and down).

Now, when we graph the ordered pair , we locate  on the x-axis.

Coordinate plane  2

In this example, the y-coordinate is . From the current position, we locate  on the y-axis.  

Coordinate plane  2 4

This is where we plot the point

Example Question #19 : Graphing

Picture11

Find the point that corresponds to the following ordered pair:

Possible Answers:

Correct answer:

Explanation:

In order to get to the point , start at the origin and move left  units and up  units.

This is point .

Example Question #1 : How To Graph A Line

Which of the following is the graph of the equation  ?

Possible Answers:

Graph_5

Graph_4

Graph_2

Graph_3

Graph_1

Correct answer:

Graph_2

Explanation:

On the coordinate plane, the graph of an equation of the form  is a horizontal line with its -intercept at . Therefore, the graph of  is horizontal with  -intercept .
