What is the equation of the trend line in the scatter plot? Use the two yellow points to write the equation in slope-intercept form. Write any coefficients as integers, proper fractions, or improper fractions in simplest form.

y = 7/5x - 21/5

Step-by-step explanation:

points to use to find slope:  (3,0) and (8,7)

slope = 7-0 / 8-3

slope = 7/5

find y-intercept (or 'b')

0 = 3(7/5) + b

0 = 21/5 + b

-21/5 = b

b = -4 1/5

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total
