Question

Write the equation for the vertical line passing through (5, 8).
A. x = 5
B. x = 8
C. x = 0
D. x = 5/8

Answer 1

A vertical line has an x coordinate that doesn't change while the y coordinate takes any value.
For it to pass through (5,8) the x coordinate will be 5 and the y value is not even shown on the formula because it doesn't matter.

Answer 2

so A?

Answer 3

Yes. A is correct.
