Question

Which is the equation of the given line?

The points to create the line are: (-5,-2) and (2,-2)

A. y= -2
B. y= -2x
C. x= -2
D. x= 2
Please explain your answer! Thanks for helping!

Answer 1

m = change in y / change in x
m = (-2 - (-2)) / (-5 - 2)
m = (0) / (-7)
m = 0

(y - b) = m (x - a)
(y - (-2)) = 0 (x - 2)
y + 2 = 0
y = -2

*where m := the gradient of a line and (a,b)

Answer 2

The final answer is A) y = -2
