Example Question #11 : How To Find Out If A Point Is On A Line With An Equation

Which of the following points is on the line 

Possible Answers:

None of these

Correct answer:

Explanation:

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  is on our line.

Example Question #12 : How To Find Out If A Point Is On A Line With An Equation

Which of the following points is found on the line ?

Possible Answers:

Correct answer:

Explanation:

To find which point is on the line, take the -coordinate, and plug it into the given equation to solve for . If the -value matches the -coordinate of the same point, then the point is on the line.

Plugging in  into the given equation will give the following:

Thus,  is on the line.
