I need to graph f(x)=-2x

Does it go, through -2 and y side of 2?

To graph the function f(x) = -2x, we need to plot some points on the coordinate plane. One way to determine these points is to substitute values of x into the function and find the corresponding y-values.

Let's start by choosing some values for x and calculating the corresponding y-values:

When x = 0, y = -2(0) = 0. So one point on the graph is (0, 0).
When x = 1, y = -2(1) = -2. So another point on the graph is (1, -2).
When x = -1, y = -2(-1) = 2. So another point on the graph is (-1, 2).

Now that we have three points, we can plot them on the coordinate plane.

The point (0, 0) corresponds to x = 0 and y = 0, so it is the origin.
The point (1, -2) corresponds to x = 1 and y = -2, so it is one unit to the right of the origin and two units below it.
The point (-1, 2) corresponds to x = -1 and y = 2, so it is one unit to the left of the origin and two units above it.

Once you have plotted these points, you can connect them with a straight line. This line represents the graph of the function f(x) = -2x.
