Question

The cost of a taxi ride is 50 cents for each 1 5 mile, , x, and a $2.50 flat fee. Which statement is correct ?

Answer 1

see the explanation

Explanation:

we know that

A linear function 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 a linear function between the total cost and the number of miles

Let

y ----> the total cost in dollars

x ----> the number of miles

The slope or unit rate is equal to

`m=(0.50)/(1.5)=\$0.33\ per\ mile`

The y-intercept is equal to the flat fee

`b=\$2.50`

substitute the given values

The linear function that model the situation is

`y=0.33x+2.50`
