The equation given is \( y = -2x \), which is a linear equation with a slope of -2 and a y-intercept of 0. This means that the graph is a straight line passing through the origin (0, 0), and the slope tells us that for every 1 unit increase in \( x \), \( y \) decreases by 2 units.

Here’s how to plot the line on the graph:

1. Start at the origin (0, 0), since there is no y-intercept term (i.e., the constant term is 0).
2. Use the slope to find the next point. The slope \( -2 \) can be interpreted as "down 2 units for every 1 unit to the right." So from (0, 0), move 1 unit to the right (to \( x = 1 \)) and then 2 units down (to \( y = -2 \)). This gives the point (1, -2).
3. You can also move to the left. From the origin, move 1 unit to the left (to \( x = -1 \)) and then 2 units up (to \( y = 2 \)). This gives the point (-1, 2).
4. Draw a straight line through these points.

The line should pass through points such as (0, 0), (1, -2), and (-1, 2), and continue following the pattern established by the slope.

**Tip:** The y-intercept is where the line crosses the y-axis, and the x-intercept is where the line crosses the x-axis. For \( y = -2x \), the y-intercept is at (0, 0).
