Question

the slope of the line that passes through the points (-2,y) and (-5,7) is -2/3. what is the value of y?

Answer 1

5

Explanation:

slope = rise/run = (7-y)/(-5-(-2)) = -2/3

3(7 -y) = -2(-3) . . . . . multiply by 3(-3)

7 -y = 2 . . . . . . . . . . . divide by 3

7 -2 = y = 5 . . . . . . . . add y-2

The value of y is 5.
