I am going to assume this is for calculus. You would need to find the derivative of each because derivative represents rate of change. The derivates are: y'=1 y'=3 y'=4 y'=2
Therefore the answer it the third choice because it has the largest derivative
The answer is y=4x+1. The rate of change is the number before x; that is, the slope of the equation. In this case 4 is the largest of all. So the third choice or equation is right.
