I NEED THIS ASAP!!!

the cost of renting a car for a day is $0.70 per mile plus a $10 flat fee.


(a) write an equation to represent this relationship. let x be the number of miles driven and y be the total cost for the day.
(b) what does the graph of this equation form on a coordinate plane? explain.
(c) what is the slope and the y-intercept graph of the relationship? explain.

Answer:


Step-by-step explanation:

$0.70 per mile is the rate (slope), $10 flat fee is your starting cost (i.e. your y-intercept).

By slope - intercept linear equations we have:

(a) y=mx+b where m is the slope and b is the y-intercept.

y=0.70x+10

(b) The graph is linear on the coordinate plane because the slope (rate) is constant.

(c) The slope of this graph is $0.70 per mile and the y-intercept is $10 flat fee.  Your cost is $10 initially and $0.70 for every mile driven.

Answer:


Step-by-step explanation:

Equation: y=0.70x + 10

It forms an increase in cost so the line slants upward.

Slope: The increase in miles per hour which is 0.70x

Intercept: Is the starting point on the y-intercept for which the line starts.Which is where the 10 comes in.(0, 10)
