Step-by-step explanation:
First of all, use substitution to find slope
(1) = m(3) - 2
3 = m3
m = 1
With both the slope and y int, you can write it in y int form
y = 1x - 2
Convert that to standard form
-x + y = -2
The total cost of the lemon cookies is $5.20
First you have to divide 32 by 4 and multiply the sum by $.65 then, you get $5.20.
5 (2f+3)=2(5f-1)
10f+15=10f-2
10f-10f=-2-15
f=-17
