Use the gradient (slope) formula: #m=(y_2-y_1)/(x_2-x_1)=(0-(-8))/(-2-(-4))=8/2=4#


The slope of a line is given by dividing the vertical 'rise' over the horizontal 'run':


It doesn't matter which point we use as 1 and which we use as 2: the math will work out to give the same slope. Don't believe me? Try it and see!
