Lesson 5.4
Enrichment and Extension
Using the Distributive Property
An electronics company sells two types of headphones. The in-ear model
costs $50. The over-the-ear model costs $100.
Store A
Store B
Store C
The table shows how
many units of each model
Stores A, B, and C want to
buy.
256
In-ear
128
192
160
Over-the-ear
96
192
1. How can the Distributive Property and mental math be used to find the total
amount the company receives from the three stores for the in-ear
headphone model?

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

what? that isnt a question
