Question

A line passes through `(1 ,5 )` and `(1 ,7 )`. A second line passes through `(3 ,6 )`. What is one other point that the second line may pass through if it is parallel to the first line?

Answer 1

A line through `(1,5)` and `(1,7)` is a vertical line; all verticals lines are parallel. So points `(3,5)`, `(3,7)`, `(3,-1000)` etc. will all be on the parallel with `(3,6)`.
