Question

What is the equation of a vertical line passing through the point (2, –3)?

y = 2

x = 2

y = –3

x = –3

Answer 1

x = 2

Answer 2

If you want a vertical line you need to look at the x coordinate. yeah that is the answer but i was going to walk you through it

Answer 3

Oh, you can walk me through it if you'd like? :)

Answer 4

if you look at the equation y = mx+b, when you have y = 2 or any number, that means the slope is zero, so it is a flat line. so you can already rule out both the y equations.

(x,y) = (2,-3) so at some point x = 2 and y = -3
while y = -3 would pass through (2,-3) it is not a vertical line because of the above.

when you have x =2 and x = -3, x = 2 goes through every y point, but x will always be 2

Answer 5

Hmm. I think I understand now. Thank you :)

Answer 6

so for y = -3 y will always be -3 no matter what x, same with x = 2, x will always be 2, even as you move up and down the y. youre welcome :)
