Astudy 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 a. an athlete drinks 7 l per day when the temperature is 80°f. b. an athlete drinks 4.4 l per day when the temperature is 80°f. c. an athlete drinks 3.85 l per day when the temperature is 80°f. d. an athlete drinks 0.55 l per day when the temperature is 80°f.

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

Step-by-step explanation:

Y-intercept of a linear model, equation or a straight line refers the point at which a line crosses the y-axis of a graph. It generally indicates a point on the graph where x equals 0.

For the equation y = 3.85 + 0.55x

At y-intercept, x = 0. Substitute x into the equation, we have:

y = 3.85 + 0.55 (0)

y = 3.85 + 0

y = 3.85

This implies that the value of fluid drank by an athlete at the starting temperature of 80°F (at x=0) is 3.85 L per day
