Answer:

Step-by-step explanation:
This is a linear graph so the equation will be in the format of y=mx+b.
b, the y-intercept, will be -3, as that is where the line crosses the y-axis.
m, the slope, is
, calculated from the change in y over the change in x from points (-4,0) to (0,-3).
Now substitute the values in our equation:

Simple steps:
1) Add the 2 items
2) Multiply by 0.75. because 25% discount = 75% of item
($72.49+$36.24)x0.75 = $81.5475 or $81.55
Your answer would be 4 you go with P.E.M.D.A.S so (5-1)= 4 then 4+4=8-4=4
