The graph shows the cost of traveling by car on a turnpike.
what is the slope of the line? write your answer as a fraction in simplest form.

The slope is

Step-by-step explanation:

The slope is the rate of change of a function, that is given by:

We are going to take the point given

x1=0.60 and y1=8

x2=2.40 and y2=32

so:

goog may have it for you

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
