$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 9 &,& -2~) 
% (c,d)
&&(~ 10 &,& 2~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{2-(-2)}{10-9}\implies \cfrac{2+2}{10-9}\implies \cfrac{4}{1}\implies 4
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-2)=4(x-9)\implies y+2=4(x-9)$

Mathematics

The independent variable is m (number of miles) and the dependent variable is e (the cost).

Step-by-step explanation:

In this situation, if you were to graph the equation on the number line ,

M will be the x and e will be the y.And we know most of the time that x is independent in that situations and y is dependent.

The cost of depends on how many miles travelled.If the cost will go up it depends on how many miles.
