The equation of the line of best fit is y = 0.5x + 25, where x is the air temperature and y is the water temperature.
What is the meaning of the slope of the line of best fit?
A. The water temperature is expected to be 0.5 °F less than the air temperature.
O B. The water temperature is expected to be 0.5 °F greater than the air temperature.
C. When the air temperature increases by 1 °F, the water temperature is expected to decrease by 0.5 °F.
O
D. When the air temperature increases by 1 °F, the water temperature is expected to increase by 0.5 °F.
r²h and you know all of your numbers other than h so you plug all that in. 100=3.14×2²×h → 100=3.14×4×h → 100=12.56×h → Divide 12.56 from both sides 100÷12.56=12.56×h÷12.56 → 7.96cm=h.
