Answer:

Length of AB = 10

Step-by-step explanation:

This can be found by using the distance formula.

Distance Formula = \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

Where

(x_1,y_1) is the first coordinate pair and (x_2,y_2) is the second coordinate pair

<em>Thus</em>

<em>x_1 = 9 and y_1 = 18</em>

<em>x_2 = 1 and y_2 = 12</em>

<em>Plugging them into the formula, we get:</em>

<em>Length = \sqrt{(y_2-y_1)^2+(x_2-x_1)^2} \\=\sqrt{(12-18)^2+(1-9)^2}. WHich is equal to 10.</em>

<em>Length is 10</em>

The format is y = mx + b
where y would be your C
x would be your M
m would be the price per mile (2.20)
and b would be your initial fee (2.75)

put this together in that format and we get
C = 2.20M + 2.75
