Can somebody explain in the simplest way how to find the slope? :)

Answer:

4/3

Step-by-step explanation:

Slope is rise over run. So how far do you rise to get up to 3 from -1. Put that over the run, (once you go up that many how far do you run?) Put that as a fraction and simplify if needed.

GrogVix [38]

Answer:

Part (A): The required expression is $55x$ .

Part (B): The correct option is C) the amount (in dollars) the company earns from each phone.

Step-by-step explanation:

Consider the provided information.

A used electronics store pays $50 for each cell phone, spends $15 refurbishing the phone, and sells the refurbished phone to a customer for $120.

Let x to represent the number of cell phones they sell.

Part (A)

For x cell phones store will pay $50x. Also store will spend $15x to refurbishing.

We will use negative sign for pay and spend money, Also use positive sign for selling amount.

Therefore the required expression is:

Company's earnings = $-50x-15x+120x$

Simplify the expression as shown.

$55x$

Hence, the required expression is $55x$ dollar

Part (B) What does the coefficient of the expression in part (a) represent?

The coefficient of the expression is the amount (in dollars) the company earns from each phone.

Hence, the correct option is C) the amount (in dollars) the company earns from each phone.
