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:
$2+$1.29(30). Multiply $1.29 times 30, and you get 38.7. Add $2 on to this and you answer is 40.7
Brand X costs $1.56 for 12 ounces
Brand X: cost of each ounce = $1.56 / 12 = $0.13
Brand Y costs 2 cents more per ounce, so the cost of brand Y per ounce= $0.13 + $0.02 = $0.15
The cost of 15 ounces of brand Y = $0.15 x 15 = $2.25
Answer
$2.25
