Question

A study was done to investigate the relationship between outdoor temperature and the amount of fluids an outdoor athlete drinks per day. The correlating linear model is shown below, where x represents the number of degrees over 80°F, and y represents the amount of fluids drank (in liters). Interpret the y-intercept

Answer 1

\[y=3.85+0.55x\]

Answer 2

is the equation they gave me

Answer 3

Answer 4

here the y-intercept, is the value of fluid drank by an athlete at x=0, namely at the starting temperature of 80°F

Answer 5

umm ok i think that made sense

Answer 6

@Michele_Laino

Answer 7

so, the number of liters of fluids, drank by an athlete is:
3.85 +0.55*0=3.85

Answer 8

at 80°F

Answer 9

ok
