Answer:
Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Step-by-step explanation:
The general formula is y = mx +b.
m = slope.
b = y-intercept of the line
19 would be the first quartile.
The toppings would still cost 0.50 each (since it is just toppings)
The large pizza costs $18 if you do not have any toppings
The medium costs half of the large
18/2 = 9
The medium costs $9 without any toppings, so your new equation will be:
c = 0.50t + 9
