Excellent choice.

You can plot three functions on the same graph there.

To graph the equation y = -x, you can use a process called plotting points. Plotting points involves choosing values for x, plugging them into the equation to calculate the corresponding y values, and then plotting those points on a graph.

Here's how you can graph y = -x using this method:

1. Choose some values for x. Let's start with x = -3, -2, -1, 0, 1, 2, and 3.

2. Substitute each value of x into the equation y = -x to find the corresponding y values.

For example:
- When x = -3, y = -(-3) = 3. So the first point is (-3, 3).
- When x = -2, y = -(-2) = 2. So the second point is (-2, 2).
- When x = -1, y = -(-1) = 1. So the third point is (-1, 1).
- When x = 0, y = -(0) = 0. So the fourth point is (0, 0).
- When x = 1, y = -(1) = -1. So the fifth point is (1, -1).
- When x = 2, y = -(2) = -2. So the sixth point is (2, -2).
- When x = 3, y = -(3) = -3. So the seventh point is (3, -3).

3. Now, plot these points on the graph. Start at the origin (0, 0) and move to each point as indicated by its coordinates.

4. Once you have plotted all the points, you can draw a straight line that passes through them. In this case, as you connect the points, you will notice that they form a straight line.

So, the graph of the equation y = -x is a straight line that passes through the points (-3, 3), (-2, 2), (-1, 1), (0, 0), (1, -1), (2, -2), and (3, -3).
