Calculus: Parallel Lines

Parallel lines

• Parallel and perpendicular lines are defined as follows:
• Parallel lines- two or more lines that do not intersect with each other, no matter what distance you move them.
• Perpendicular lines- two or more lines that intersect at a 90 degree angle.

What if we don't have a line that's exactly equal to 0?
Rephrasing, instead of x + 1/2 y = 0, what if we had x + 1/2 y = 1?
Consider having the line x plus 1/2 y being equal to 0.
x+1/2y=0
And then another line, x plus 1/2 y being equal to 1.

x+1/2y=1
