Use graphing technology (TI calculator or Desmos) to find the linear regression equation that models the data. Let x equal the hours of sleep and y equal test score. Explain the steps you use. Use the equation to determine the approximate test score of a student who sleeps an average of 7.5 hours a night. Show your work. (please no links or nonsense answers)

i don't know i don't know

hey there! : )

4y < -4

we need to isolate y. we can do this by simply dividing both sides by 4.

4y ÷ 4 > -4 ÷ 4

simplify.

y > -1

5 - y > 0

once again, we need to isolate y, so we can start off by subtracting 5 from both sides.

5 - y - 5 > 0 - 5

simplify.

-y > -5

divide both sides by -1.

** remember that when dividing any side by a negative, you must switch the sign! **

-y ÷ -1 < -5 ÷ -1

simplify.

y < 5
