GCSE Secondary Maths Age 13-17 - Graphs: Mid Point - Explained

The video tutorial explains how to find the midpoint of a line segment given two points, A and B, with coordinates. It details the process of calculating the X and Y coordinates of the midpoint by finding the mean of the respective coordinates of the two points. The tutorial emphasizes the straightforward nature of the calculation and provides tips for remembering the formula.

What are the coordinates of point A?

• (2, 3)

• (8, 6)

• (6, 8)

• (3, 2)

How do you calculate the X coordinate of the midpoint?

• Add the X coordinates of A and B, then divide by 2

• Divide the X coordinate of A by B

• Subtract the X coordinate of B from A

• Multiply the X coordinates of A and B

What is the Y coordinate of the midpoint of line AB?

• 5

• 3

• 11 / 2

• 4

What is the best way to remember how to find the midpoint?

• Multiply the coordinates

• Subtract the coordinates

• Find the mean of the X and Y coordinates

• Divide the coordinates

How many marks were awarded for knowing how to calculate either the X or Y coordinate?

• Four marks

• One mark

• Three marks

• Two marks
