Find distance between points A3 -4 and B-1 3 Solution. YA means the y-coordinate of point A. Now label the coordinates of points A and B.
Practice finding the distance between two points on the coordinate plane that share the same x- or y-coordinate.
Given two points you can always plot them draw the right triangle and then find the length of the hypotenuse. The distance formula is not complicated -- you just need to practice with a graph so you understand whats going on. The distance between 32 and 78 is sqrt 52 or approximately 721 units. The horizontal distance a is xA xB The vertical distance b is yA yB Now we can solve for c the distance between the points.
