Question

Please answer number 5. find the slope of each line. tell what the slope represents.

Answer 1

In order to find the slope of the line, we need to divide the change in the y-coordinates by the change in the x-coordinates.

Using the points (3, 1200) and (6, 800), we have that:

$m=\frac{\Delta y}{\Delta x}=\frac{800-1200}{6-3}=-\frac{400}{3}=-166.67$

The slope of this line is -166.67.

The slope means the increase or decrease in y for each unitary increase in x.
