Use an equation to find the value of k so that the line that passes through the given points has the given slope. (
shutvik [7]

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (4, -4) and (k, -1) and the slope m = 34.

Substitute:

\dfrac{-1-(-4)}{k-4}=34\\\\\dfrac{3}{k-4}=\dfrac{34}{1}\qquad|\text{cross multiply}\\\\34(k-4)=3\qquad|\text{use distributive property}\\\\34k-136=3\qquad|+136\\\\34k=139\qquad|:34\\\\k=\dfrac{139}{34}
