Answer 1

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.

Answer 2

slope formula
\[m=\frac{ y_2-y_1 }{ x_2-x_1 }\]

Take (1, 75) and (2, 60). Plug it into the equation.

Answer 3

okay what should i get

Answer 4

@sourwing

Answer 5

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

Answer 6

okay

Answer 7

i got 5

Answer 8

is that wrong

Answer 9

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.

Answer 10

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

Answer 11

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