Question

Find the value of r so the line that passes through the pair of points has the given slope. (6, 8), (r, −2), m=1

Answer 1

r=-4

Explanation:

use the slope formula

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

Then plug in x and y values and set that equal to m=1

1=
`(-2-8)/(r-6)`

multiply r-6 over

r-6=-10

r=-4
