in the xy plane, is point(2,-3) on line l?
(1) Point (-2,3) is on line l
(2) l is not perpendicular to the x axis
OA:E
(1) Point (-2,3) is on line l
(2) l is not perpendicular to the x axis
OA:E
S1:Point (-2,3) is on line l
Can be yes.Can be No
S2:l is not perpendicular to the x axis
Again, Can be yes.Can be No
Together,there is possibility that line l may pass or may not pass through the point (2, -3)
