Question

silver city public pool
the equation for the line of best fit is ( y = 2.5x - 50 ). according to the equation, which of these statements is true?
on a day with a high temperature of ( 60^{circ}f ), the attendance would likely be about 150 people.
on a day with a high temperature of ( 80^{circ}f ), the attendance would likely be about 150 people.

Explanation:

Step1: Substitute \(x = 60\) into the equation \(y=2.5x - 50\)

$$y=2.5\times60-50$$
$$y = 150 - 50$$
$$y=100$$

Step2: Substitute \(x = 80\) into the equation \(y = 2.5x-50\)

$$y=2.5\times80-50$$
$$y=200 - 50$$
$$y = 150$$

Answer:

On a day with a high temperature of \(80^{\circ}F\), the attendance would likely be about \(150\) people.
