Question

Which pair of points forms a vertical line segment?
(-3,5) and (5,-3)
(4,-2) and (4,3)
(-8,1) and (5,1)
(2,3) and (-2,5)

Answer 1

It will be the one that has no change in x value, because a vertical line is only changing the y value.

Answer 2

what?

Answer 3

The x value is the first number you see in an ordered pair. Look at the second pair of points. The x stays the same (4 both times).

Answer 4

Answer 5

No no we're looking at x value not y value. C is a horizontal line because y value doesn't change.
