    Try to convert the first function into slope-intercept form by finding the slope and plugging it into y=mx+b. It'd be easier to compare with the second function.

    slope formula \[m=\frac{ y_2-y_1 }{ x_2-x_1 }\] Take (1, 75) and (2, 60). Plug it into the equation.

    Plug it into the equation. 60 - 75 / 2 - 1.

    Okay, welp you're supposed to actually to subtract the numbers first then divide them. \[m = \frac{ 60 - 75 }{ 2-1 }\] Once you get the slope, plug it into the slope-intercept formula. y = mx+ b. That'll get you something you can compare to the second function.

    you know that in function 1 , $15 is spent, and in function 2 $12 is spent

    so the function with $15 would be the greater rate of change
