the graph represents function 1, and the equation represents function 2:
function 2
y = 5x + 4
how much more is the rate of change of function 2 than the rate of change of function 1?
2
3
4
5

Function 1 :
you have a horizontal line...and rhe rate of change (slope) of a horizontal line is 0.

function 2 :
y = 5x + 4in y = mx + b form, the rate of change (slope) will be in the m position. Therefore, the rate of change in this one is 5.

difference being : 5 - 1 = 4
