Y=mx+b, m=(y2-y1)/(x2-x1)
m=(7-4)/(6--3)=3/9=1/3
y=x/3 +b, now use either point to solve for b, I'll use (6,7)
7=6/3 +b
7=2+b
b=5 so our line is:
y=x/3 +5 or more neatly...
y=(x+15)/3
You need to write the entire function: y = f(x) = 2x + 6.
Here the input quantity is x, and the output is y (or f(x)).

Answer:
30 pencils
Step-by-step explanation:
Given :
Number of pencils shared = 40
Sharing ratio = 2 : 6
Nimah's share = (2 / sum of ratio) * number of pencils
Nimah's share = (2 / 8) * 40
Nimah's share = 80 / 8
Nimah's share = 10 pencils
Jack's share = total number - Nimah's share
Jack's share = 40 - 10
Jack's share = 30
