Which of the following functions has the steepest slope?

A. y = - 3x-4

B. y = 2x+3

C. y=-4x+1

D. y=x+6

The one with the steepest slope would be the equation that will have the highest value of m regardless of the sign. From the choices, I believe the correct answer is option C. It is y=-4x+1 that has the steepest slope where m is equal to - 4, the negative would indicate the direction of the slope.
