Best ResponseYou've already chosen the best response.0Y = mx + b is the slopeintercept form of the equation of a line m = slope b = y intercept so graph something simple such as y = 2x2. Then double the slope (m, which is 2 in this case) and intercept (2 in this case) to get y = 2x2 > y = 4x4. Both slope and intercept are doubled, but as you can see it crosses the xintercept (where y = 0) at the same point as y = 2x2. The x intercept is not changed. as long as m = b, the xintercept will always be the same.
