Review of Geometry

Consider the points A (-4, 5) and B (6, -10). Which of the following correctly evaluates the distance between the points?

• √((6 - (-4))² + (-10 - 5)²)

• √((6 + (-4))² - (-10 + 5)²)

• √((5 - (-4))² + (-10 - 6)²)

• √((6 - 4)² + (5 - 10)²)

Consider the points A (-4, 5) and B (6, -10). Given that √((6 - (-4))² + (-10 - 5)²) evaluates the distance between the points, which of the following is correct rounded to the nearest tenth?

• √(250) ≈ 15.8

• √(275) ≈ 16.6

• √(300) ≈ 17.3

• √(325) ≈ 18.0

Consider the points A (-4, 5) and B (6, -10). Which of the following correctly evaluates the midpoint between the points?

• x_m = (-4 + 5)/2 & y_m = (6 + -10)/2

• x_m = (-4 - 5)/2 & y_m = (6 - (-10))/2

• x_m = (-4 + 6)/2 & y_m = (5 + -10)/2

• x_m = (-4 - 6)/2 & y_m = (5 - (-10))/2

Consider the points A (-4, 5) and B (6, -10). What is the midpoint between these points?
