Can some one help me answering these four questions?? I think I have the correct answer for the last two but im not really sure
1. how do you find the distance between two points on the coordinate plane?
2. how do you find the slope between 2 points on the coordinate plane?
3. what do you have to see as evidence to be convinced that the 2 lines are parallel?
4. what do you have to see as evidence to be convinced that 2 lines are perpendicular?
