Answer 1

as long as (a) and (b) are real numbers

Sounds like I have a friend that thinks a little outside the box! It is valid as long as the letters a and b are real numbers

Answer 3

haha, thank you - it's a homework question & i have to argue why or why not.

Answer 4

how can i explain why it will form a line if they are real numbers only? i have to go somewhat in depth..
