Question 120374: I'm taking an Algebra 2 exam tomorrow and trying to review as best I can but I can't remember everything we've gone over in the semester. I was just wondering about parallel equations. How can you tell that the equation is in fact parallel so you don't have to work it all out and notice it once you see it? Thanks.

:
If the equations have the same slope (m), they are parallel
:
In the slope/intercept form (y = mx + b), it is very obvious,
if the equation are not in this form, do the operations to put them in this form:
:
For example:
y = x + 6
is parallel to
y = x - 3
