Question

A pizza shop charges 2.50 for a slice of cheese pizza and an additional 0.50 for each topping

Answer 1

Y=2.50x +0.50

Explanation:

the equation for this question (which what I think your asking for, please tell me if that's not the question)

Every equation of this type starts with Y=

Then you take the slope which the original price (2.50).

then you take the additional price (.5)

You can find both of these things by asking yourself what is the price for one slice with nothing on it? That's the original price. Then to find the additional price you ask what is the extra price?

To make the equation you set it up like this:

Y= (original price) x (you always add x after this) + (if its positive - if negative) (then the additional price)

The original price is the slope. The additional price is the Y-intercept.

Y=(slope)x +(y-intercept)

Then fill in the blanks

Y=2.50x+ 0.5
