Question

can u plzz help me............

Answer 1

from the qn (x,y) is the mid point of (a+b,b-a) and (a-b,a+b) so
(x,y)
$\frac{x1 + x2}{2} \: \frac{y1 + y2}{2}$
x=a+b+a-bwhole divide2 and
y=b-a+a+bwhole divide2
x=2a/2 and y=2b/2
x=a and y=b
LHS=bx=ba. because x=a
RHS=ay=ab=ba. because y=b
therefore LHS=RHS
It's bx=ay.

Answer 2

Hey User !! Let x1 = a + b
x 2 = a - b

y1 = a - b
y2 = a + b


• A mid point divides a line into 1:1 ratio.
