Answer :

Slope is calculated as the change in y over the change in x so you would need to do 5- (-5) which turns the negative sign to a positive making it 5+5=10 and the same thing with the 2s 2-(-2)=4 so the answer would be 10/4 or 5/2. Billy did the reciprocal.

Answer:

The slope of the line is the inverse of the answer he gave, 5/2.

Step-by-step explanation:

In this case, the slope equation for a line is:

[tex]m\frac{y2-y1}{x2-x1}[/tex]

Analyzing the description, we can appreciate that Billy the x values by the y values, that is incorrect, because the equation is as shown before. So the slope of the line is the inverse of the answer he gave, 5/2.
