## cc33 2 years ago Choose the slope-intercept equation of the line that passes through the point (-5, -1) and is perpendicular to y = 5/2x + 2. A. y = 2/5x + 1 B. y = -5/2x -27/2 C. y = -2/5x - 3 D. y = 5/2x + 23/2

1. zordoloom

What is the slope of this line: y = 5/2x + 2?

2. cc33

idk

3. cc33

is it like the same thing we did last time?

4. zordoloom

no

5. cc33

oh. i forgot how to do this then

6. zordoloom

have you seen this equation before: y=mx+b?

7. cc33

yes

8. zordoloom

m is the slope is If you look at the equation y = 5/2x + 2, can you see how it's the same format?

9. cc33

oh yeah

10. zordoloom

So if you compare it to the format of y=mx+b, and if "m" represents the slope, can you find the slope of y = 5/2x + 2?

11. cc33

12. zordoloom

no

13. zordoloom

But you are close.

14. zordoloom

The question asked for a perpendicular line to y = 5/2x + 2

15. zordoloom

That means that it will be negative inverse

16. zordoloom

so it will look like -2/5

17. cc33

ohhhhh okay

18. cc33

so its B

19. zordoloom

no

20. zordoloom

It's C

21. cc33

oh thank you. Im really thankful of you helping me. :)

22. zordoloom

yep!
