Y=-2x

This is an equation of a straight line in slope-intercept form, where the slope (m) is -2 and the y-intercept (b) is 0.

To graph this line, you can start by plotting the y-intercept at the point (0, 0). Since the y-intercept is 0, this means the line passes through the origin.

Then, use the slope to find additional points. The slope of -2 means that for every increase of 1 in the x-coordinate, the y-coordinate decreases by 2. So from the point (0,0), you can go down 2 units and 1 unit to the right to get the point (1, -2). Similarly, you can go down 2 units and 1 unit to the left to get the point (-1, -2).

You can continue this process to find more points, or if you want to make your graph more accurate, choose additional x-values and find the corresponding y-values using the equation. Once you have a few points, you can connect them with a straight line to graph the equation y = -2x.

The graph of y = -2x will be a straight line, sloping downwards from left to right.
