The slope of ab is 2/5 . a(3, k) is a point on the line ab. find k if b(-7, 0).

slope of any line with 2 points is,

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

In this case,

m=2/5

(x1,y1)=(3,k)

(x2,y2)=(-7,0)

So,

》2/5=(0-k)/(-7-3)

》2/5=-k/-10

》k=20/5

》k=4

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 : )
