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

## Example Questions

### Example Question #1 : How To Do Coordinate Geometry

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 #1 : How To Do 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 #282 : Geometry

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 #1 : 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 #284 : Geometry

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 .
