Point A is located at (−4, 9) on the coordinate plane. Point B is located at (−4, −7) . What is the distance between Point A and Point B?

Answer 1

Point 1 (x_{a ,} y_a) = (-4 , 9)

Point 2 (x_{b ,} y_b) = (-4 , -7)

Objective :

Find the distance between two given points on a line?

Formula :

distance between two points √(x_b - x_a)² + (y_b - y_a)^2√

√(-4 + 4)² + (-7 - 9)^2√

√(-16)² => √256 => 16

Distance between points (-4 , 9) and (-4 , -7) is 16
