Question

The distance of point C1,2) from the line
x+y+5= o measured along the line parallel
to 3x-y =7 equal to​

Answer 1

Answer:

C

40

Distance is measured along a line whose is equal to line 3x−y=7

So slope of line which passes through (1,2) is 3 and hence equation of line is 3x−y=1

Now we have two equation

3x−y=1 and x+y=−5

On solving we get

x=−1 and y=−4

Now using the distance formula, we have

=

(1+1)

2

+(2+4)

2

=
