Question

the equation for the line of best fit is y = 2/3x + 1/3. according to the equation, which of these statements is true? the shoveling time increases by about 3 hours for every 2 inches of snowfall. the shoveling time increases by about 2 hours for every 3 inches of snowfall.

Explanation:

Step1: Identify slope - intercept form

The equation of the line is $y=\frac{2}{3}x+\frac{1}{3}$, where the slope is $\frac{2}{3}$.

Step2: Interpret slope

The slope $\frac{2}{3}$ means for every 3 - unit increase in $x$ (snowfall in inches), $y$ (shoveling time in hours) increases by 2 units.

Answer:

The shoveling time increases by about 2 hours for every 3 inches of snowfall.
