Midpoint and distance in the coordinate plane

What you'll learn

1. Calculate the midpoint of a line segment using M = ((x1 + x2)/2, (y1 + y2)/2)
2. Calculate the distance between two points using d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
3. Apply the midpoint formula to find a missing endpoint when one endpoint and the midpoint are known
4. Use the distance formula to determine segment lengths in coordinate geometry problems

Prerequisites

• Slope-intercept, point-slope, and standard forms
