Enter 2 points below:

|-|-|-|-|-|-|--|-|-|-|-|-|-|
  

A line has an endpoint of 2

It has a midpoint of 5

We need to calculate Point 2

Point 2 Formula

Point 2 = (2 * Midpoint) - Point1

Evaluate with M = 5 and P1 = 2

Point 2 = (2 * 5) - 2

Point 2 = 10 - 2

Point 2 = 8





What is the Answer?
Point 2 = 8
