Hank found the slope of the line going through (-2,7) and (-1,7) using the calculation at the right. Do you agree or disagree with his answer? If you disagree, correct his mistake and give the correct slope.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

answer is  

c.

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
