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.

y = 3.85 + 0.55x

Answer 1

An athlete drinks 0.55 L per day when the temperature is 80°F.

An athlete drinks 3.85 L per day when the temperature is 80°F.

An athlete drinks 7 L per day when the temperature is 80°F.

Answer 5

Brandon has a 55-gallon fish tank. He estimates he can drain the tank at an average rate of 11 gallons per minute. In a linear model of this situation, x represents the number of minutes the tank has been draining. Relative to this situation, what does the y-intercept represent?
The y-intercept represents the amount of water in the tank before it has been drained.

The y-intercept represents the rate at which the tank can be drained.

The y-intercept represents the number of minutes it takes to drain the tank.

The y-intercept represents the amount of water in the tank after it has been drained.
