Question

Reallyyy need helpppppppppp

Answer 1

r = 3

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' =
`(y_2-y_1)/(x_2-x_1)`

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

8 =
`(2+6)/(4-r)`

8(4 - r) = 8

4 - r = 1

r = 4 - 1

r = 3
