A company is evaluating a new biology program that is supposed to improve test scores. The box plots show the results of biology tests given before and after using the program. With this data, what is the most reasonable answer to the question: Does the program improve test scores?

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!

my answer was deleted because it was to vague the answer is 12.76 becuase its in the hundreths place. john
