Question

Choose the equation of the vertical line passing through the point (-4, 2).

Answer 1

if it's a vertical line, and from (-4, 2) (x, y) coordinates x = -4, y = 2


if y = 3, or y= 4, or y = 5
what do you think "x" will be equals to?

Answer 2

x=2?

Answer 3

im confused...

Answer 4

y=mx+b

Answer 5

notice the line, is VERTICAL, x is ALWAYS -4

Answer 6

even if y = 1,000,000, x = -4
thus the equation is x = -4

Answer 7

wow, I got it. thanks

Answer 8

what about if the line is horizontal?

Answer 9

The horizontal line is the x axis.

Answer 10

so for this example it would also be -4?

Answer 11

Yes

Answer 12

y = 2, x = -4
the line is horizontal
if x = -5, y = 2
x = -7, y = 2
x = -1,000,000, y = 2
x = 2,000,000, y = 2

thus
y = 2

Answer 13

thank you.
