Solution:

We have been given the data of cost of Gas in two months these are May and September

The cost of Gas in month of may is $3.53 per gallon

The cost of Gas in month of September is $3.05 per gallon

We have to determine the percentage change in the cost of gas

% change in cost of gas = 13.59 %

So, the price of the Gas was decreased by 13.59% from may to september

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

0,0
