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.

$y = - 2 x$

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=-2xFinding the point by putting the values.

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

Now the points are $(0, 0), (1, - 2), (2, - 4)$

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

Step 5. Draw the lines through the three points.
