## Esmy 3 years ago Determine whether the lines will be perpendicular when graphed. 3x - 2y = 6 2x + 3y = 6 A. Yes B. No

1. Snipa420

First, convert the equations to y=mx+b format. This makes everything easier.

2. Esmy

Okay ...

3. Esmy

is it no :s ?

4. Snipa420

Are you actually trying to figure it out, or are you just making people tell you the answers

5. Esmy

I actually tried ://// math isn't easy for me I guess I'm just that dumb.

6. Snipa420

y=3x/2 -3 y=-2x/3+2

7. Snipa420

perpendicular lines have slopes that are negative inverses of each other

8. Snipa420

So if a line has a slope of 3x/2, then a line that is perpendicular to it has a slope of -2x/3

9. Snipa420

(hint hint)

10. Esmy

Oh okay its yes :D

11. Esmy

:B ...

12. Snipa420

Do you understand what makes lines perpendicular?

13. Esmy

To make a line perpendicular to that line you have to take the "negative recipricol" of the first slope.

Yep you got it! Have fun with the rest of your homework
