Question

write the equations of a line which passes through origin and points on the line lie in second and fourth quadrant.

Answer 1

Hi ,

Equation of the  line whose slope is m and passes through the origin 

is in the form of y = mx 

i ) if m > 0  the line lie first and third quadrant 

ii ) if m < 0 the line lie second and fourth quadrant

Therefore , if take m = any negative rational number we can write 

required equations which passes through origin and lie 2 nd and 4 th 

quadrant.

example:

1 ) y = - x 

2 ) y = -2x 

3 ) y = -3x

4) y = - 1/2  × x

5) y = (-3/2 ) × x

etc ..,

I hope this will useful to you .
