Question 87928
How can you prove that a point (x, y) is not located on a line of a given equation. Show example to explain.
------------------------
Is the point (1,5) on the line y = 3x + 7
-------------
Substitute x=1 and y=5 into the equation to see if you get a true statement.
5 = 3*1 + 7
5 = 3 + 7
5 = 10
-----------------
That's not true.  That point is not on that line.
