Answer:
see the explanation
Explanation:
we know that
A linear function in slope intercept form is equal to
![f(x)=mx+b](https://img.qammunity.org/2020/formulas/mathematics/middle-school/6y17ezrpv7ir4zbcfli9dye6jyqxdod420.png)
where
m is the slope or unit rate
b is the y-intercept
x is the independent variable or input value
f(x) is the dependent variable or output value
In this problem we have
![f(m)=5+3m](https://img.qammunity.org/2020/formulas/mathematics/middle-school/dujfc4bphnmq4nzjadxyl2bzjep92mb7yi.png)
where
m is the number of miles
f(m) is the cab company's fare in dollars
we have that
In this context
Slope
The slope or unit rate is equal to the cost per mile for the riders trip
The slope is $3 per mile
Y-intercept
The y-intercept is the cost of the riders trip when the number of miles is equal to zero, also is called the initial value.
The y-intercept is $5
