How do you know if two lines are paralell, perpendicular or neither based on slope? Ifthe slope is 2/3 on one, what is the other?

and slope perpendicular slopes are *NEGATIVE RECIPROCAL* If slope of first equation is 4/5 then slope of perpendicular line is negative 5/4

5. Nnesha

parallel lines have same slope if slope of first equation is 2 then slope of 2nd equation is also 2

6. Nnesha

and slope perpendicular slopes are *NEGATIVE RECIPROCAL* If slope of first equation is 4/5 then slope of perpendicular line is negative 5/4

THANKYOU SO MUCH!:D

What if it is parallel? @Nnesha

@AaronAndyson ?

11. anonymous

or neither?

12. AaronAndyson

Perpendicular : slope is NEGATIVE RECIPROCAL Parallel : slope is same

No idea :(

15. Nnesha

if slopes are not same and not perpendicular then neither example if slope of first equation is 2 and slope of 2nd equation is 3 os neither

$$\color{blue}{\text{Originally Posted by}}$$ @domisreallytall What if it is parallel? @Nnesha $$\color{blue}{\text{End of Quote}}$$ parallel lines have the same slope so if slope of first equation is 3 then slope of 2nd equation is also 3
