# ISEE Middle Level Math : How to find the points on a coordinate plane

## Example Questions

### Example Question #1 : How To Find The Points On A Coordinate Plane

Which of the following points will you find on the -axis?      Explanation:

A point is located on the -axis if and only if it has -coordinate (first coordinate) 0. Of the five choices, only fits that description.

### Example Question #3 : Coordinate Geometry

Which of the following points is on the -axis?      Explanation:

A point is located on the -axis if and only if it has a -coordinate equal to zero.  So the answer is .

### Example Question #3 : How To Find The Points On A Coordinate Plane

A line segment on the coordinate plane has its endpoints at the points with coordinates and . Give the midpoint of the segment.     Explanation:

The -coordinate of the midpoint can be found by dividing the sum of the -coordinates of the endpoints by 2: The -coordinate of the midpoints is found similarly: ### Example Question #4 : How To Find The Points On A Coordinate Plane

A line segment on the coordinate plane has its endpoints at the points with coordinates and . Give the coordinates of the midpoint of the segment.     Explanation:

The -coordinate of the midpoint can be found by dividing the sum of the -coordinates of the endpoints by 2: The -coordinate of the midpoint is found similarly: .

The correct response is .

### Example Question #5 : How To Find The Points On A Coordinate Plane

A line segment on the coordinate plane has its endpoints at the points with coordinates and .  Give the coordinates of the midpoint of the segment.     Explanation:

The -coordinate of the midpoint is half the sum of the -coordinates of the endpoints:      The -coordinate of the midpoint is found similarly:        The correct response is .
