Mathematics

Answer:

y = 3

Step-by-step explanation:

Use the slope formula:

        y2 - y1

m = ------------- ,     which here becomes

         x2 - x1

          y - 5          -1

m = -------------  = -----

        8 - (-2)          5

Solve this for x.  Cross multiplication yields:

5y - 25 = -1(10) = -10

Then 5y = 15, and y = 3
