Question

Scarlett is selling popsicles at her school’s fair. She wants to make sure she has enough popsicles to last the entire day, so she keeps track of the number of popsicles remaining throughout the day. This scatter plot shows the data along with the line of best fit.

The equation for the line of best fit is y = -15x + 149. According to the equation, which of these statements is true?
Scarlett sold about 149 popsicles per hour.
Scarlett likely had about 149 popsicles at the start of the day.

Quizzma Team · Answer

The correct statement is: Scarlett likely had about 149 popsicles at the start of the day. Explanation: In the equation of the line of best fit, ( y = -15x + 149 ), the ( y )-intercept (the value of ( y ) when ( x = 0 )) is 149. This means that at the beginning of the day (when ( x = 0 )), Scarlett had approximately 149 popsicles. The slope of -15 indicates that she sells 15 popsicles per hour, so she does not sell 149 popsicles per hour.

According to the equation, which of these statements is true? Scarlett sold about 149 popsicles per hour. Scarlett likely had about 149 popsicles at the start of the day.
