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.
Answer:
HCF = 
Step-by-step explanation:
A common factor is a factor that is shared by two or more numbers (or, in this case, polynomials). The highest common factor (HCF) is found by finding all common factors of the two expressions and selecting the largest one.
Find HCF of 
Factor 
Factor out common term: 
Factor
: 
Factor 
Factor out common term: 
Factor
: 
Therefore, from inspection the HCF =
