Find the slope of the line. (Please explain if you can, and answer in an integer/fraction.)

-2

Step-by-step explanation:

We can find the slope of a line by using two points

(-2,1) and (2,-7)

The slope is given by

m = (y2-y1)/(x2-x1)

   = (-7-1)/(2- -2)

   = (-8)/(2+2)

   = -8/4

   =-2

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 : )
