Question

Suppose the length of a line segment joining the players of Mid-on be 10 units. If

coordinates of its one end are (2,-3) and the abscissa of the other end is 10 units,then its

ordinate is
​

Answer 1

Answer: 3 or -9

Step-by-step explanation:

Let the Ordinate of B are (10,y) and A are (2,-3)

AB²=(10-2)²+(y+3)²

100=64+y²+6y+9

y²+6y-27=0

y²+9y-3y-27=0

y(y+9)-3(y+9)=0

(y+9)(y-3)=0

y=-9 or 3
