What is the slope of the line in the graph?

The slope of the line is: 1

Step-by-step explanation:

The slope of a line can be calculated with this formula:

Then, you need to choose two points of the line shown in the graph and substitute them into the formula for calculate the slope:

Let's pick the points (1,2) and (-3,-2).

Substituting:

Simplifiying,  you get that the slope of the line in the graph is:

The slope of the line is: 1

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
