Question

Sarah is renting a car for her weekend trip to the mountains. The total cost of the rental, y, as it relates to the number of miles driven, x, is shown in the graph below.
Fill in the blanks so that the functions below, written to represent this situation, are correct. If necessary, answer in terms of a decimal, rounded to the nearest hundredth.

ƒ(x) = ________ a0 x +________ a1

If you answer I will give brainliest.
(I'm running out of ideas to get help)

Answer 1

I believe it would be y=1/2x+5 because the y-intercept is 5 and the slope is 1/2.

Answer 2

Answer:

f(x) = 0.5x + 5

Step-by-step explanation:

The total cost of the rental, y, as it relates to the number of miles driven, x.

Here the x-axis represents the miles driven and y-axis represents the cost of the rental.

From the given graph, the fixed fee is $5.

Now let's find the rate per mile which is nothing but the slope.

Slope = Rise / Run

Rise is nothing but change in y-values and Run is change in x-values.

Slope = 2/4        [Rise = 2 and Run = 4]

Slope = 1/2 = 0.5

Therefore, the rate per mile is 0.5 dollars and fixed cost is $5

f(x) = 0.5x + 5, where "x" represent the number of miles.
