Easy, that is the slope from (2,f(2)) to (3,f(3))

remember that the slope between the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)

find f(2) and f(3)
f(2)=2²+6(2)+5=4+12+5=21
f(3)=3²+6(3)+5=9+18+5=32

so the slope from (2,21) to (3,32) is (32-21)/(3-2)=11/1=11

answer is 11

-2/3-5/6= write in simplest form

-2/3 - 5/6

We need common denominators so, since 3 can go into 6, we only need to multiply the first fraction by 2.

= -2 x 2 / 3x2 - 5/6
= -4 / 6 - 5/6

We only subtract the numbers that are in the numerators,

= -4-5 / 6
= -9/6

Both nine and six are divisible by 3, so to put into lowest terms...

=-9÷3 / 6÷3
= -3/2 <--- Final Answer
