MCQ
The equation $x^2-7 x y+12 y^2=0$ represents
- ACircle
- BPair of parallel straight lines
- CPair of perpendicular straight lines
- ✓Pair of non-perpendicular intersecting straight lines
✓
Answer
Correct option: D.
Pair of non-perpendicular intersecting straight lines
(D) $x^2-7 x y+12 y^2=0$
$\Rightarrow(x-3 y)(x-4 y)=0$
Hence, the lines are intersecting and non-perpendicular.
$\Rightarrow(x-3 y)(x-4 y)=0$
Hence, the lines are intersecting and non-perpendicular.
