# Distance between two points, midpoint (Coordinate Geometry)

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

Solve the following questions.

1. If point A (x,1) and point B (1,-2) are 5 unit apart. What could be the value of x?
2. 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.

1. x = 5 or -3
2. (1,-3)
