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.

3. anonymous

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

okay what should i get

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

7. anonymous

okay

8. anonymous

i got 5

9. anonymous

is that wrong

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
