George sold 18,22,26,12,25,20 and 19 cars per month over the past seven months. He followed the steps below to determine the number of cars he needs to sell in the next month to have a mean number of sales per month of 24. Where did George make his first mistake

i think it might be a but you might want a second opinion

none.

step-by-step explanation:

m

=

5

m1=5

b

=

−

1

b=-1

find the slope and y-intercept of the second equation.

b=-6

compare the slopes

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
