Answer:
1. slope m = 1; y-intercept b = 3
2. slope m = ; y-intercept b = 4
3. slope m = 3; y-intercept b = 1
4. slope m = [tex]\frac{1}{2}[/tex]; y-intercept b = 1
5. the slope demonstrates the cost of toppings PER topping and how the price increases per topping. the y-intercept is the starting cost WITHOUT toppings (when toppings = 0) and the slope increases the price starting with the y-intercept because it is the initial cost. the graph is attached
