How can you determine if two lines are parallel? Give an example

Question

mertsj · Answer

See if they have the same slope.  y = 2x -7 if parallel to y = 2x + 3 because both have slope 2

anonymous · Answer

____________
____________   { these are example of parallel lines, because they do not intersect}

anonymous · Answer

you will first need to prove that they are parallel by various theorems and postulates such as the converse of the alternate interior angles theorem, and others

anonymous · Answer

what kind of math are you in and what is the specific problem you need help with?

anonymous · Answer

Bob, I have algebra 1 and it gets confusing for me with graphing..

anonymous · Answer

Mertz and KMcNamara, thanks for the example, greatly appreciated..

anonymous · Answer

Bob, what are theorems and postulates, I'm confused..

anonymous · Answer

hey, sorry for the late reply, I had violin lessons and was unable to continue answering questions. 

Theorems and postulates are what you will find and use in Geometry. This is why I asked what level of math you were in and so I understand why you do not know about theorems and postulates :)

hope this helps!
