Question

find the coordinates of the mid point (8,9) and (2,-9)​

Answer 1

Answer:

(8,9) - first quadrant

(2,-9) - fourth quadrant

Answer 2

Answer:

(x2,y2) = √(x2-x1) ²+(y2-y1) ²

= √ (x-8)²+ (y-9) ²------------------------------------------1

and (x2,y2) = √(x3-x2) ²+(y3-y2) ²

= √(2-x) ²+(-9-y) ²--------------------------2

from 1 nd 2 we get,

√(x-8)²+(y-9)²= √(2-x)²+(-9-y)²

squaring both sides

(x-8) ²+(y-9) ² = (2-x)²+(-9-y)²
