@souvik

2. souvik Group Title

find what is the slope of the line k...let m be that slope... $m=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }$

3. SNIIX18 Group Title

Which one is y 2 −y 1 x 2 −x 1

4. SNIIX18 Group Title

so its 0 right

5. souvik Group Title

any of those two...its 1/0 that means Undefined... these lines are parallel to y axis..
