What is the distance formula for a line segment in a coordinate plane?

• sqrt((x2 - x1)^2 + (y2 - y1)^2)

• sqrt((x2 + x1)^2 + (y2 + y1)^2)

• x2 - x1 + y2 - y1

• (x2 - x1) + (y2 - y1)

What are the steps to calculate the length of a line segment using the distance formula?

• Identify the coordinates of the two endpoints of the line segment and use the Pythagorean theorem: d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

• Use the midpoint formula to find the coordinates of the midpoint of the line segment

• Divide the line segment into equal parts and count the number of parts

• Identify the coordinates of the two endpoints of the line segment and use the distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
