Question

A line contains the points (-2, 4) and (5, 4). Its equation is.....
A. y = x + 7
B. y = x + 2
C. y = x + 5
D. y = 4
E. Cannot be determined

Answer 1

find the slope first...can you do that ?

Answer 2

thanks

Answer 3

sometimes

Answer 4

slope(m) = (y2 - y1) / (x2 - x1)
(-2,4) -- x1 = -2, y1 = 4
(5,4) -- (x2 = 5, y2 = 4)

lets sub the stuff in
m = (4 - 4) / (5 - (-2)
m = 0 / 7

The slope is 0, so it is a horizontal line.
Therefore the equation is y = 4.

Answer 5

any questions ?

Answer 6

no, but thanks that helped

Answer 7
