Answer:
casual = y=1.5(10)+0 and heavy = y= .50(10)+20
Step-by-step explanation:
casual;
1.50 = your slope
10 is your x because it can change
and it starts at 0 because there's no flat rate making your y-intercept 0.
This makes your equation y=1.5(10)+0
heavy;
.50 = slope
10 is also your x here
this one starts at 20 on the graph because it is the flat rate and thus, the y-intercept.
This makes this equation y=.50(10)+20
