Lines n Stuff Flashcards
1
Q
If 2 lines are parallel what does that mean about its slope?
A
That means they have the same slope but different y-intercepts.
2
Q
If 2 lines are parallel, what does that mean? About the # of solutions & about the lines?
A
There are “no solutions”. The lines will never intersect.
3
Q
How should you use a calculator to solve parallel line equations?
A
Convert them to standard form, their slopes are equal so set them equal. Then go to the numeric solver and solve.
4
Q
What does a perpendicular line mean in relation to the OG line?
A
It means it intercepts it once
5
Q
If line B is perpendicular to line A, what does that mean about its slope? (slope of A = -2/4x)
A
It means the slope is flipped, it’s + and now 4/2x.
