is the point-slope form of a line. I mention this one first because we are given a point on a line and told to find it's equation. All we lack is a slope.

We are told though, that this particular line is PARALLEL to the line defined as . To be parallel means that our two lines have the same slope correct? Knowing that, we have the slope of as and we can then plug that back into our point-slope form of a line.

All that is left to do at this point (no pun intended) is to put it into slope-intercept form.
