The required graph is:

Step by step solution

Step 1. Given information.

The equation $y = - \frac{2}{5} x - 3$ .

Step 2. Find slope and y-intercept.

Compare the given equation $y = - \frac{2}{5} x - 3$ with the slope-intercept form $y = m x + b$ .

$m = - \frac{2}{5}; b = - 3$

So, slope is $- \frac{2}{5}$ and y-intercept is -3.

Step 3. Graph the line using y-intercept and slope.

Plot the y-intercept $(0, - 3)$ and for second point, use the slope which is given as $- \frac{2}{5}$ that is;

$r i s e = - 2, r u n = 5$

So, plot the second point at $(5, - 5)$ .

Then, graph the line joining these two points:
