Step-by-step explanation:
To subtract, you must first:
Find like denominators.
- Note: What you do to the denominator, you must do to the numerator.
- If there is an equal sign, and there are fractions on both side, what you do to one side, you do to the other.
Simplify:

Take for example, a question such as:
7 3/10 - 9/20
First, change the mixed fraction into improper fraction:
7 = (7/1) * (10/10) = 70/10 + 3/10 = 73/10
Find common denominators. Remember that what you do to the denominator, you do to the numerator. Multiply 2 to both numerator and denominator:
(73/10)(2/2) = (146/20)
Simplify. Combine like terms
146/20 - 9/20 = 137/20
Simplify.
137/20 = 6 17/20
6 17/20 would be your answer for the example question.

Answer:
Step-by-step explanation:
Since we know the line goes through points 
and 
, we can construct a line in slope-intercept form
where 
is the slope and 
is the Y-intercept.
The slope can be found using the two points provided:
The line is now represented as
To solve for , we can plug in one of the two points:
We know have our line:
To determine if the point 
falls on this line, we just plug the numbers into the equation and see if it holds true:
This does not hold true, so the point is not on the line.
