Answer:
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
Step-by-step explanation:
Part 1) we know that
The linear equation in slope intercept form is equal to
[tex]y=mx+b[/tex]
where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
[tex]y=2.50+2.20x[/tex]
This is a linear equation in slope intercept form
where
[tex]m=2.20[/tex]
[tex]b=2.50[/tex]
Part 2) we have that
x -----> represent the number of miles
y ----> represent the total charge in dollars
The slope is
[tex]m=\$2.20\ per\ mile[/tex] ---> unit rate
The y-intercept is
[tex]b=\$2.50[/tex] ----> 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
