Plug this into the formula y2 - y1 / x2 - x1

-2 = x1, x2 = 2, y1 = -1, y2 = -3

-3 - (-1) / 2 - (-2)

-2 / 4

-1/2

The slope is -1/2.

Lets do this step by step:

1 wall = 1 whole or $\frac{1}{1}$
Jacob painted $\frac{3}{4}$ of the wall
$\frac{1}{1} - \frac{3}{4} = \frac{1}{4}$ (because $\frac{3}{4}$ is a quarter of 1 whole)
His little brother painted $\frac{1}{2}$ of the wall
$\frac{1}{4}-\frac{1}{2} =$
Find the common denominator which is 4:
1/4 × 1 = 1/4 and 1/2 × 2 = 2/4
$= \frac{1}{2}$ (because a half of 1/4 is 1/2)
