For this case we have:
By definition, two points are needed to find the equation of a line. We have a series of points given by:
We chose two points:
By definition, the formula of the slope is given by:
Substituting:
Being a line of the form 
, we substitute a point and the slope found to find the cut point b.
Thus, the equation of the line is given by:
Answer:
Option C
If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).
The money is taken per hour of work and 125 is the amount taken per hour of work
and when multiplied by .095 gives the amount extra he has to pay(for the tax)
Using Pythagoras Theorem,
(12)^2+ (a)^2= (13)^2
144+a^2= 169
a^2= 169-144
a^2= 25
a= √25
a= 5mm
Hope it helps you.
