A line segment has endpoints R(-8, 4) and S(5, -3). Which statement BEST explains the relationship between the length of line segment RS and the coordinates of the endpoints?

• RS² = (-8 - 5)² + (4 - (-3))² because RS is the hypotenuse of a right triangle with side lengths equal to the difference in x- coordinates and the difference in y-coordinates
• RS² = (-8 - 5)² + (4 - (-3))² because RS is equal to the sum of the differences in x coordinates and y coordinates
• RS = (-8 - 5)² + (4 - (-3))² because RS is equal to the sum of the differences in x coordinates and y coordinates
• RS = (-8 - 5)² + (4 - (-3))² because RS is the hypotenuse of a right triangle with side lengths equal to the difference in x- coordinates and the difference in y-coordinates
