m= (y2-y1)/(x2-x1)
OpenStudy (michele_laino):
the requested slope m, is given by the subsequent formula:
\[m = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}}\]
where (x_1, y_1) and (x_2,y_2) are two points which belong to your line. So picking the first two points, and substituting their coordinates, into the formula above, we get:
\[m = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}} = \frac{{ - 3 - \left( { - 5} \right)}}{{0 - \left( { - 3} \right)}} = ...?\]
