Answer:
-2
Step-by-step explanation:
y=-2x+5
y=mx+b where m=slope and b=y-intercept
-1/2 because slope is the rise over the run. If you count on the grid from one point on the line to another you go up one and 2 to the left meaning the slope is 1/2, buttttt when the line decreases going to the right, it has a negative slope so you just add a - sign in front
12*$.73=$8.76-$7.68=$1.08 So it is $1.08 cheaper to buy it by the case.
Hope that helps.
