Y=-2x

This is a linear equation in slope-intercept form. The equation represents a straight line in the Cartesian coordinate system where the slope is -2 and the y-intercept is 0.

To further analyze the equation, you can plot the line. Choose some values for x, substitute them into the equation, and solve for y. For example, if you choose x = 0, then y = -2(0) = 0. Therefore, one point on the line is (0, 0).

Similarly, if you choose x = 1, then y = -2(1) = -2. Another point on the line is (1, -2).

You can continue this process to find more points and then plot them on a graph. Alternatively, you can also find the slope, which is -2, and use it to determine the rise and run from one point to another to plot the line accurately.

Remember, the slope of -2 means that for every 1 unit increase in the x-coordinate, the y-coordinate decreases by 2 units.
