Question

There are many beautiful picnic sites along the Elk Range hiking trail. This scatter plot shows the elevations and the high temperatures yesterday at some of those picnic sites. It also shows the line of best fit.
The equation for the line of best fit is y=
–
1
100
x+85. Based on the equation, which of these statements is true?

Answer 1

1100

Answer 2

The slope is −1/100, so for each 1 foot increase in elevation the predicted temperature drops 0.01°F (equivalently, for each 100‑foot increase it drops 1°F). The y‑intercept 85 means at elevation 0 the predicted high temperature is 85°F.
