The graph of the equation is

Step by step solution

Step 1. Given Information

In the given exercises we have to graph by plotting points.

$y = - \frac{4}{5} x - 1$

Step 2. Find three points whose coordinates are solutions to the equation.

You can choose any value forx andy.

In this case sincey is isolated on the left side of the equation. It is easier to choose values ofx.

Step 3. The given equation is y=-45x-1Finding the point by putting the values.

$x = 0 x = 5 x = 10 y = - \frac{4}{5} x - 1 y = - \frac{4}{5} x - 1 y = - \frac{4}{5} x - 1 y = - \frac{4}{5} \times 0 - 1 y = - \frac{4}{5} \times 5 - 1 y = - \frac{4}{5} \times 10 - 1 y = 0 - 1 y = - 4 \times 1 - 1 y = - 4 \times 2 - 1 y = - 1 y = - 4 - 1 y = - 8 - 1 y = - 1 y = - 5 y = - 9$

Now the points are $(0, - 1), (5, - 5), (10, - 9)$

Step 4. Plot all points in a rectangular coordinate system.Plot the points (0,-1), (5,-5), (10,-9)

Step 5. Draw the lines through the three points.
