Question

Write an equation in point-slope form of the line having the given slope that contains the given point. m=56m=56m (30,12)

Answer 1

Point-slope form is $y-y_1=m(x-x_1)$, where the point $P(x_1,y_1)$ lies on the graph and m is the slope of the graph.

We have a point (30, 12) and a slope of 56.

So we write $y-12=56(x-30)$. And we're done.
