The cost in dollars, y, of a large pizza with x toppings from pat’s pizzeria can be modeled by a linear function. a large pizza with no toppings costs $14.00. a large pizza with 2 toppings costs $17.50.

what is the cost of a pizza with 5 toppings? round to the nearest penny.

We can translate the problem and given into data points: (0, 14) and (2,17.50).We solve for the slope of the two points, that is (17.50 - 14)/2 equal to 1.75. Hence substituting in the point-sope form standard formula: y - y1 = m (x-x1) then y - 14 = 1.75 x , when x is 5, y is equal to $22.75
