The equation representing pizza purchase and delivery in point slope form is y = 2x + 1 and the delivery fee is $1
The total cost of pizza including delivery can be broken down thus :
- Cost per pizza
- Number of pizza purchased
- Delivery fee (this is a constant)
General form of a point slope equation :
- y = a + bx
- y = total cost
- a = intercept (Constant)
- b = slope(cost per pizza)
- x = number of pizzas purchased
From the question :
- Total cost including delivery = $9 = y
- Cost per pizza = $4 = b
- Number of pizzas = 2
Putting the values into the equation :
9 = 4(2) + a
Solve for a
9 = 8 + a
9 - 8 = a
a = 1
This means that delivery fee is $1
The equation in point slope form is thus : y = 2x + 1
