Lines n Stuff

Question 1

If 2 lines are parallel what does that mean about its slope?

Answer 1

That means they have the same slope but different y-intercepts.

Question 2

If 2 lines are parallel, what does that mean? About the # of solutions & about the lines?

Answer 2

There are “no solutions”. The lines will never intersect.

Question 3

How should you use a calculator to solve parallel line equations?

Answer 3

Convert them to standard form, their slopes are equal so set them equal. Then go to the numeric solver and solve.

Question 4

What does a perpendicular line mean in relation to the OG line?

Answer 4

It means it intercepts it once

Question 5

If line B is perpendicular to line A, what does that mean about its slope? (slope of A = -2/4x)

Answer 5

It means the slope is flipped, it’s + and now 4/2x.
