The given equation is in the form of a line, which is y = mx + b, where m = slope and b = y-intercept.
Let's rewrite the given equation as y = –2x + 0. We can see that m = –2 and b = 0. To graph the line, we start from the y-intercept, which is b = 0 in this case. That means we start from the origin. The slope m = –2 tells us that we'll move 2 units down when moving 1 unit to the right. So this is how the line looks like.
