Question

(3,y) (1,4) m= -2 what is the value of y if the line through the two given points is to have indicated slope

Answer 1

y=0

Explanation:

The equation for the slope is

m = ( y2-y1)/(x2-x1)

-2 = (4-y)/(1-3)

-2 = (4-y)/-2

Multiply each side by -2

4 = 4-y

Subtract 4 from each side

4-4 = 4-y-4

0 = -y

0=y
