M + f = 15....multiply by -5
3m + 5f = 51
-----------------
-5m - 5f = - 75 (result of multiplying by -5)
3m + 5f = 51
----------------add
-2m = - 24
m = -24/-2
m = 12 <=== 12 multiple choice questions

Answer:
y=3/2x-6
Step-by-step explanation:
m=(0-(-3))/(4-2)
m=(0+3)/2
m=3/2
y-y1=m(x-x1)
y-(-3)=3/2(x-2)
y+3=3/2(x-2)
y=3/2x-6/2-3
y=3/2x-3-3
y=3/2x-6
It would cost $1.07
