Answer:
y=3x+5
Step-by-step explanation:
Point slope equation:
y=mx+b
m-slope, b- is y-intercept
equation given 2 points
y-y1 = m(x-x1)
For point (1,8) and slope m=(y2-y1)/(x2-x1) = 20-8/5-1=12/4=3
y-8 =3(x-1)
arange it in point slope format
y-8=3x-3
y=3x-3+8
y=3x+5
Do you need it in fraction or decimal?
Answer: The required percentage is 75% of print area filled with advertisement.
Step-by-step explanation:
Since we have given that
Part of the print area of the newspaper carried new = 
Rest was filled with advertisements = 
So, Percentage of the print area was filled with advertisement is given by

Hence, the required percentage is 75% of print area filled with advertisement.
Just plug in 2 for x since f(x) = f(2)
f(2)=2^2+1
f(2)=4+1
f(2)=5
