Answer:
Vertical lines: lines that run up and down. If you are standing up then you are vertical. On a graph the x-axis has little marks that run up and down or "vertical." Since the x-axis has lines that run vertical then if you have a point use you x-ordinate (x number). Therefore; in the point (4, -3), your vertical line is x = 4.
In the point (2, 10), can you determine the vertical line ...
Step-by-step explanation:
Right you figured it out x = 2.
For vertical line just take the other number and write y =.
