Question

find the equation of the straight line which is perpendicular to the line 2x + Y =3 and passes through the point (1,1)​

Answer 1

Correct option is

B

Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

Given lines

x+y+4=0

x=−y−4-----(1)

3x−y−8=0-(2)

from eq (1) and (2)

3(−y−4)−y−8=0

−3y−12−y−8=0

−4y=20

y=−5

from eq(1)

x=+5−4

x=1

point of intersection P(1,−5)

eq of line from point A(2,−3) and P(1,−5)

y+3=

1−2

−5+3

(x−2)

y+3=

−1

−2

(x−2)

y+3=2x−4

2x−y−7=0

if two line are perpendicular then

m

1

m

2

=−1

But the reason is not correct for statement
