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 ?

see the explanation

Step-by-step explanation:

we know that

A linear function in slope intercept form is equal to

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

The y-intercept is equal to the flat fee

substitute the given values

The linear function that model the situation is

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
