Question

A pizza buffet has prepared 16 pizzas on the line at the beginning of lunch at 11:00am. The equation used to describe the total numbers of pizzas that have been placed out on the buffet line is shown below. Y=12X+16 If x represents every 6 minutes after 11:00 a.m, which statement best describes the rate of change in the number of pizzas set out on the buffet?

Answer 1

Every 12 minutes, 24 more pizzas were set out on the buffet.

Explanation:

we know that

The equation of the line in slope intercept form is given by

`y=mx+b`

where

m is the slope b is the y-intercept

we have

`y=12x+16`

so

The slope or unit rate is equal to

`m=12\ (pizzas)/(6\ minutes)`

That means

Every 6 minutes, 12 more pizzas were set out on the buffet.

or

Every 12 minutes, 24 more pizzas were set out on the buffet.
