Question

Which answer is the equation of the given line?
Coordinates are -5, -2 and 2, -2

A.X=2
B. X= -2
C. Y= -2
D. Y= -2x
Got 100% on this test...THE ANSWER IS C

Answer 1

Can you find the slope of this line?

Answer 2

Well, actually, don't even bother with the slope.
Notice how the y cord stays the same at y=-2

Answer 3

So its C?

Answer 4

When the x cords are the same, it means that it's a vertical line
When the y cords are the same, it means that it's a horizontal line

When the line is vertical, you only have an x value
When the line is horizontal, you only have a y value

and yep, it's C

Answer 5

Thanks again!
