Question

find the equation of a straight line through the point (-1,5) and making an angle of 135 degree with the positive direction of x-axis​

Answer 1

Answer:

Answer

Line passes through the point (1,5).

It makes angle 135

o

with x-axis. Therefore,

Slope, m = tan135

o

=−1

Equation of line is

y−y

1

=m(x−x

1

)

y−5=−1(x−1)

y−5=−x+1

x+y−6=0

Hence, option D is correct.
