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.

$y = - 4 x$

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

You can choose any value for x and y.

In this case since y is isolated on the left side of the equation. It is easier to choose values of x.

Step 3. The given equation is y=-4xFinding the point by putting the values.

$x = 0 x = 1 x = 2 y = - 4 x y = - 4 x y = - 4 x y = - 4 \times 0 y = - 4 \times 1 y = - 4 \times 2 y = 0 y = - 4 y = - 8$

Now the points are role="math" localid="1647584609826" $(0, 0), (1, - 4), (2, - 8)$

Step 4. Plot all points in a rectangular coordinate system.Plot the points (0,0), (1,-4), (2,-8)

Step 5. Draw the lines through the three points.
