# Distance between two points, midpoint (Coordinate Geometry)

**Distance between two points, midpoint (Question)**

Solve the following questions.

- If point A (x,1) and point B (1,-2) are 5 unit apart. What could be the value of x?
- Point C (3,0) is a midpoint between point A (5,3) and pont B. What is the coordinate of point B?

*Guide:*

**Distance between two points**: Using Pythagoras theorem**Midpoint**: x-coordinate and y-coordinate of a midpoint is the average of the x-coordinates and y-coordinates of two points.

**Distance between two points, midpoint (Answer)**

- x = 5 or -3
- (1,-3)
