Problem
Given the line 
and a point on this line equidistant from the coordinate axes. Such a point exists in:
Solution
If a point is equidistant from the coordinate axes, then the absolute values of the x-coordinate and y-coordinate are equal. Since the point is on the line , find the intersection point of 
and and the intersection point of 
and .
Substituting 
for 
in results in 
, so 
. That means 
, so one of the points is in the first quadrant.
Substituting 
and in results in 
, so 
. That means 
, so the other point is in the second quadrant.
Thus, the points are in quadrants 
and 
, so the answer is 
.
