This video tutorial explains how to calculate the distance between two points and the midpoint of a line segment in a rectangular coordinate system. It introduces the distance and midpoint formulas, followed by solving two example problems to demonstrate their application. The video concludes with an invitation to explore more lessons at the Math District.

What are the two main topics covered in this video?

• Slope of a line and the equation of a circle

• Distance between two points and the midpoint of a line segment

• Distance between two points and the slope of a line

• Equation of a line and the distance between two points

What is the formula for the distance between two points (x1, y1) and (x2, y2)?

• D = (x2 - x1) + (y2 - y1)

• D = sqrt((x2 - x1)^2 + (y2 - y1)^2)

• D = (x2 + x1) / 2 + (y2 + y1) / 2

• D = (x2 - x1)^2 + (y2 - y1)^2
