How to determine the midpoint of two points

The video tutorial covers the process of finding midpoints between two points on a coordinate plane. It begins with an introduction to points and labeling them with subscripts to avoid confusion. The teacher explains how to find the midpoint by averaging the x and y coordinates of two points. A practical example using a number line is provided to illustrate the concept. The midpoint formula is derived and demonstrated, showing how to calculate the midpoint using the formula (X1 + X2) / 2, (Y1 + Y2) / 2.

Why do we use subscripts when labeling points in coordinate geometry?

• To make calculations easier

• To confuse students

• To differentiate between multiple points

• To make the points look more complex

What is the midpoint between the numbers 4 and 8 on a number line?

• 9

• 7

• 6

• 5

How can you find the midpoint between two numbers on a number line?

• Multiply the numbers and divide by two

• Subtract the smaller number from the larger one

• Add the numbers and divide by two

• Find the difference and add it to the smaller number

What is the formula for finding the midpoint between two points (X1, Y1) and (X2, Y2) on a coordinate plane?

• (X1 * X2) / 2, (Y1 * Y2) / 2

• (X1 / X2), (Y1 / Y2)

• (X1 + X2) / 2, (Y1 + Y2) / 2

• (X1 - X2) / 2, (Y1 - Y2) / 2

If you have points (-2, 1) and (6, 3), what is the midpoint?

• (0, 0)

• (2, 2)

• (4, 2)

• (3, 1)
