Answer:
correct answer is 5/2
Explanation:
the mistake was the student took the difference of the x-values and it in the numerator and the difference of the y-values should be the denominator
5-(-5) / 2-(-2) = 10/4 or 5/2
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.
