1. ## Slope Question, Help please!

Find the value of r so the line that passes through each pair has the given slope.

1. $(-5, r), (1, 3), m = \frac{7}{6}$

2. (-7, 2), (-8, r), m = -5

2. Slope = rise/run
Slope = ${y_2} - {y_1} / {x_2} - {x_1}$

1)

Let -5 be ${x_1}$ and 1 be ${x_2}$ and
Let r be ${y_1}$ and 3 be ${y_2}$

Plugging in, we get the equation

3 - r / 1 - (-5) = 7/6
3 - r / 6 = 7/6
3 - r = 7
r = -4
