Answer 1

Answer:

r = 3

Step-by-step explanation:

Slope of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by the formula,

Slope 'm' = $\frac{y_2-y_1}{x_2-x_1}$

Slope of a line passing through (4, 2) and (r, -6) is 8.

8 = $\frac{2+6}{4-r}$

8(4 - r) = 8

4 - r = 1

r = 4 - 1

r = 3
