I need help on questions 8 and 9.

for number 8 b=-2 m=0.5 y= 0.5x-2

for number 9 b= i don't know

Step-by-step explanation:

the line goes through -2 to get b. m crosses through somewhere around the 0.5 line to estimate you would say. the equation you are looking for would be y=mx+b

find out the value of b

step-by-step explanation:

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
