Answer

Explanation:

Step1: Analyze the slope - intercept form

The equation of the line is $y = 200x+750$, where $y$ is weekend sales and $x$ is the number of online reviews. In the slope - intercept form $y = mx + b$ ($m$ is the slope and $b$ is the y - intercept).

Step2: Interpret the slope

The slope $m = 200$, which means for each increase of 1 in $x$ (each additional online review), $y$ (weekend sales) increases by 200. So the statement "A bookstore’s weekend sales likely increase by $750 for each online review" is false.

Step3: Interpret the y - intercept

When $x = 0$ (no online reviews), we substitute $x = 0$ into the equation $y=200x + 750$. Then $y=200\times0 + 750=750$. So a bookstore that doesn't have any online reviews could expect to have about $750 in weekend sales.

Answer:

A bookstore that doesn't have any online reviews could expect to have about $750 in weekend sales.
