Question

If point P(4, 7) is on line l, what is the equation of line l in slope intercept form?

point slope equation is:

Answer 1

A. y=2x-9

Explanation:

A. Parallel lines have the same slope. That means the line y=2x+3 has the same slope as any line parallel to it. So the slope is 2.

Using m=2, substitute it and (4,-1) into the point slope form and simplify to find the y-intercept.
