y - 3 = 2(x + 5)
This is a point-slope form of a linear equation. The two key features in this equation is the point (x0, y0) and the slope, m = rise/run. Lets rewrite it in a general formula.
y - y0 = m(x - x0)
We can identify that the point is at (-5, 3), where x0 = -5 and y0 = 3, and the slope is m = 2.
