Question

find x if the distance between points A and B is 13 and point B is located in the second quadrant. A=(5,-1) B=(x,4)

Answer 1

The points are A = (5, - 1) and B = (x, 4) and the distance between these points is 13 and point B is located in the second quadrant.

The distance between two points is .

The point B = (x, 4) lies in second quadrant, so the x - coordinate is negative.

Therefore point B = (- 7, 4).
