m=X
XXXXXXXX in general is y=XX+b where b XX XXXXXXXXX
For XXXXXXXXXXX it XXX XX use point B(6,11)
So we XXXX XXXX y=11 and x=6 XXXX put in XXX equation
Y=XX+b
11=2×X+b
b=-X
so XXXXXXXX XX = 2 − 1
For doing so first XXXXXXXXX slope of the perpendicular XXXXXXXX
Midpoint XX AB are (
,
)=(X,X)
Slope of XXX XX XXX XXXXXXXXX from above points as
= = X
m=2
and that XX the Perpendicular XXXXXXXX XX− of AB so will XX -
XXX we XXX XXXXXXXXX XXX intercept using (X, 9) and m XX -1/X
we XXX
9=− ×5+b
and y =-12hence these XXX XXX coordinate XX point C
b=11.X
now equation XX
X= − + XX.5 is
(XXX)
Let’s XXXX XXX equation of XXXX XX XXXXX is XXXXXXXXXXXXX XX XXXX AB having equation XXXXX is y=2x-X XXXXXXXXXXXXX line XX one XXXX XXX a negative, reciprocal XXXXX to another.
So AC will have XXXXXXXX y=-1/2x-1
XX y will XX XXXX for the point c either we XXX XXXXXXXX of BC or XXXXXXXX XX so XX can XXX XXXX XXXXX
-X/2x-1=-XX+45
X.5x=46
X=92/5
