Question

the equation for the line of best fit is y = -\frac{1}{100}x + 85. based on the equation, which of these statements is true? a picnic site at an elevation of 2,200 feet likely had a high temperature of about 63 degrees yesterday. a picnic site at an elevation of 2,300 feet likely had a high temperature of about 50 degrees yesterday.

Explanation:

Step1: Substitute x - value

Given the equation $y =-\frac{1}{100}x + 85$, substitute $x = 2200$.

Step2: Calculate y - value

$y=-\frac{1}{100}\times2200 + 85$. First, $-\frac{1}{100}\times2200=- 22$. Then $y=-22 + 85=63$.

Step3: Check the second statement

For $x = 2300$, $y=-\frac{1}{100}\times2300+85=-23 + 85 = 62
eq50$. So the first statement is true.

Answer:

A. A picnic site at an elevation of 2,200 feet likely had a high temperature of about 63 degrees yesterday.
