The definition of slope is change/difference in y values divided by change/difference in x values.
So considering any point (x,y) on the line, and point (-3,-7)
%28y-%28-7%29%29%2F%28x-%28-3%29%29=-2 --> %28y%2B7%29%2F%28x%2B3%29=-2 --> %28y%2B7%29=-2%28x%2B3%29
That would be the point-slope form of the equation (including the given point), but the slope-intercept form is my favorite, because it is unique to each line:
y%2B7=-2x-6 --> y=-2x-13
