The positive solutions of the equation ax + by + c = 0 always lie in the
a. 1st quadrant
b. 2nd quadrant
c. 3rd quadrant
d. 4th quadrant

Solution:

Consider the positive solutions as (p, q)

As p which is the abscissa is positive, it will lie towards the positive direction of x-axis

As q which is the ordinate is positive, it will lie towards the positive direction of y-axis

So (p, q) will lie on the first quadrant

Therefore, the positive solutions will lie in the 1st quadrant.
