The slope of a line is [latex] \frac{y_2 - y_1}{x_2 - x_1} [/latex]. We have the points (3, -2) and (1, 8). Let's substitute those into the formula.  [latex] \frac{8 - (-2)}{1-3} [/latex] subtracting a negative is the same as adding, so that makes our equation [latex] \frac{8+2}{1-3} [/latex] [latex] \frac{10}{-2} [/latex] slope = -5
