Question

Help please.... I under stand some parts but not the graph parts I need to know where to graph

Answer 1

Choose some numbers for pizza (x), like, x=1, 2, 3, 4, 5

Then find the corresponding values of y for every value of x.

when x=1, and y=20; y=12+8(1)=20

when x=2,y=28

when x=3, y=36

when x=4, y=44

Then go to the graph, identify the point where x=1 on the Pizza-axis, and where y=20 on the cost axis, then trace these points till they intersect, the point of intersection is where the line graph passes.

Repeat the above steps for the point where x= 4 on the Pizza-axis, and y=44 on the cost-axis.
