Slope is defined as rise over run. Rise being the vertical distance the line travels and run being the horizontal distance. When plotted on a graph and traveling left to right this line drops two points, so the rise is -2. The run is 4. In fractional terms the slope is -2/4, or -1/2. -1 devided by 2 gives you the answer of -0.5, or negative one-half.

Negative 1/2. You always do y2-y1 / x2-x1. So, 0--2 is 2 (add). -1-3 is -4. Then rise over run (y over x). The slope is 2/-4. This is -1/2.

m = (0 + 2) (-1 - 3)
m = 2 / (- 4)
m = (-1 / 2) ie negative one half.

Use the equation (Y1-Y2)/(X1-X2) so (-2-0)/(3- -1)
-1/2
