What is the formula for finding the midpoint of a segment?

• (x1 / x2) / 2, (y1 / y2) / 2

• (x1 + x2) / 2, (y1 + y2) / 2

• (x1 - x2) / 2, (y1 - y2) / 2

• (x1 * x2) / 2, (y1 * y2) / 2

What is the formula for finding the distance between two points?

• D = (x2 * x1) + (y2 * y1)

• D = (x2 + x1) / 2 + (y2 + y1) / 2

• D = (x2 - x1) + (y2 - y1)

• D = √((x2 - x1)^2 + (y2 - y1)^2)
