Question

I need help with these two

Answer 1

Part 1) Slope-intercept form

Part 2) The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee

Explanation:

Part 1) we know that

The linear equation in slope intercept form is equal to

`y=mx+b`

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

`y=2.50+2.20x`

This is a linear equation in slope intercept form

where

`m=2.20`

`b=2.50`

Part 2) we have that

x -----> represent the number of miles

y ----> represent the total charge in dollars

The slope is

`m=\$2.20\ per\ mile` ---> unit rate

The y-intercept is

`b=\$2.50` ----> initial value or flat fee

therefore

The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee
