(a)

The linear equation is $\"\"$ , where $\"\"$ is the charge of the rental space at the market (in dollars).

Graph :

Graph of the function $\"\"$ :

$\"\"$ axis : Rental charge per space.

$\"\"$ axis : Number of spaces.

Rental charge per space and number of spaces cannot be a negative.

Graph the function for the positive values of $\"\"$ and $\"\"$ .

$\"\"$

(b)

The function is $\"\"$ .

Compare the linear equation with slope-intercept form of line equation $\"\"$ .

Slope $\"\"$ .

The slope $\"\"$ represents that for every 1 dollar increase in rental space, the number of spaces rented decreases by 4.

Observe the graph:

$\"\"$ intercept is 200 and $\"\"$ intercept is 50.

The $\"\"$ intercept represents spaces available for no rental charge.

The $\"\"$ intercept represents rental charge of $ 50 when nobody will rent any space at the flea market.
