given A(-2,3) and AB = 10 units. if ordinate of B is 9, find the abscissa of B. Share with your friends Share 4 Manbar Singh answered this Let the coordinates of point B are Bx,9Now, we have A-2,3 s the given point.Now, we know that distance between points x1,y1 and x2,y2 is D = x2-x12 + y2-y12Now AB = 10 units⇒x+22 + 9-32 = 10⇒x+22 + 36 = 100⇒x+22 = 64⇒x+2 = ±8⇒x+2 = 8 or x+2 = -8⇒x = 6 or x = -10Hence abscissa of point B is either 6 or -10. 3 View Full Answer Man answered this 6 and -10 1
