Answer:
The y-intercept is the flat fee for the pizza - $5. The slope is the charge for each additional topping - $.50
Step-by-step explanation:
c=.5m+5
y=mx+b - slope intercept formula
In the slope-intercept formula, the 'b' is the y-intercept. We know that would be the flat fee because there is no variable attached to it.
In that formala, m is the slope and is attached to a variable, x. This problem uses the variable m instead of x, but we can see that the slope for .5m would be .5. Thus, that's the charge for the toppings. Hope that helps!
