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.
