mathmate · Answer

The point-slope form of a line is the following:
y-y1=m(x-x1)
where m is the slope, and (x1,y1) is a point through which the line passes.

The form y=mx+b is the slope-intercept, m=slope, b=y-intercept.

For the given problem, you need to rearrange the given equation to the point-slope form and choose accordingly.
