Question

Angles made by the lines represented by the equation xy+y=0 with y-axis are..?
​

Answer 1

SOLUTION

TO DETERMINE

Angles made by the lines represented by the equation xy + y = 0 with y-axis

EVALUATION

Here the given equation is

xy + y = 0

Which can be rewritten as

y ( x + 1 ) = 0

Which gives two lines y = 0 & x + 1 = 0

Therefore the line xy + y = 0 represents two lines y = 0 & x + 1 = 0

Now the line y = 0 is equation of x axis

So it makes an angle 90° with y axis

Again the line x + 1 = 0 is equation of the line parallel to y axis

So it makes an angle 0° with y axis
