Step by step solution

Step 1. Given Information.

The given slope is $m = \frac{- 2}{3}$ .

Step 2. Slope of a line.

To model a line on a geoboard, we need the rise and the run.

Use the slope formula.	$m = \frac{r i s e}{r u n}$ .
Replace $m$ with $\frac{- 2}{3}$ .	$\frac{- 2}{3} = \frac{r i s e}{r u n}$ .

So, the rise is 鈭�2 and the run is 3.

Step 3. Geoboard.

Since the rise is negative, we choose a starting peg on the upper left that will give us room to count down. We stretch the rubber band down 2 unit, then go to the right 3 units, as shown.

The hypotenuse of the right triangle formed by the rubber band represents a line whose slope is $\frac{- 2}{3}$ .
