Question

What's (8,-2) (r,-6), m =-4

Answer 1

m is simply the slope of the line. The equation for m or slope is given as:

m = (y2 – y1) / (x2 – x1)

Therefore we can find for r by substituting the values:

- 4 = (-6 – (-2)) / (r – 8)

- 4 = - 4 / (r – 8)

r – 8 = 1

r = 9

So:

(r, -6) = (9, -6)
