Example Question #2 : How To Find Out If A Point Is On A Line With An Equation
Which point is NOT on the line 
A point is on a line if, plugged in, it creates a true mathematical equation.
For example, 
The point that does not work is 
Since this is not true, the point is NOT on the line.
Example Question #6 : Other Lines
The equation of a line is given below:
which point below can be found is NOT on the line?
To find the solution to this problem just do a quick check, pluggin in each point's x and y value into the equation. Remember coordinates are written with the x-value first, then the y-value (x,y).
If you try each point the only one that doesn't work is (8,2) !
In other words, if the x-value is 8 the y-value should be 4!
Example Question #81 : Coordinate Geometry
Which of the following points is on the line
None of these
To ascertain if a point is on a line we must plug that coordinate pair into the equation of the line. If a true statement such as 5=5 is returned then we know that point is on our line.
Choose the point you suspect is on the line.
Since the equation returned a true statement the point
