Catherine found that as she increases the price of a chocolate bar, the number of sales per week decreased.

week - number of sales
1 - 149
2 - 143
3 - 137
4 - 131
5 - 125

a. write a formula for the arithmatic sequence that represents the number of sales per week.

b. exlain how you could use the information to predict the number of sales for the eighth week.

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
