Answer:
If the line is parallel to the x-axis than only x value changes and y value remains constant.
Step-by-step explanation:
Consider the provided information.
We need to draw three lines that are parallel to the x-axis.
The required graph is shown below:
Now the ordered pairs for points on each line is:
For line y=-3 The ordered pairs are (-1,-3), (0,-3) and (1,-3)
For line y=2 The ordered pairs are (-2,2), (2,2) and (3,2)
For line y=4 The ordered pairs are (-3,4), (0,4) and (4,4)
Here we can observe the x value changes but y values remains constant.
Therefore, if the line is parallel to the x-axis than only x value changes and y value remains constant.
