Answer:

8

Step-by-step explanation:

  • m = (Y2-Y1) ÷ (X2- X1)
  • 2 = (10-c) ÷ (-1-(-2))
  • 2 = (10-c) ÷( 1)
  • 2= 10-c
  • c = 10-2
  • c= 8

(-2,c) and (-1,10)

10-c

-1--2

10-c

1

We need the fraction to be 2, or 2/1. The bottom number is 1, so we technically already have the answer. But we still need to plug in a number for c. To get 2, we need to subtract 8 from 10.

So c is 8.
