## ChristineToTheRescue 3 years ago Help me check my slope question?

1. ChristineToTheRescue

Write the equation of a line (in slope intercept form) that is perpendicular to y=1/4x-6 that passes through the poin (6,4)

2. ChristineToTheRescue

I MEAN 1/2

3. ChristineToTheRescue

y=1/2x-6

4. ChristineToTheRescue

So... isn't that already slope intercept form?

5. ChristineToTheRescue

I'm really confused...

6. CalebBeavers

thats the slope intercept form of the line it is perpendicular to. you're trying to find the other line.

7. ChristineToTheRescue

So, I have to reciprocal it?

8. Mertsj

What is the slope of y = 1/4x-6?

9. ChristineToTheRescue

OH. I see nao.

10. ChristineToTheRescue

Pshhh.

11. ChristineToTheRescue

so it becomes y=-1/2-6 correct?

12. CalebBeavers

No, you have to take the slope, reciprocal it and change the sign, and then use that plus the point you have to find the equation of the other line

13. ChristineToTheRescue

Oh wait. I'm a derp. I just realized that :P

14. ChristineToTheRescue

y-4=-2(x-6) yes?

15. CalebBeavers

correct, not distribute the -2 and after that add the 4 to both sides and you're done

16. CalebBeavers

now*

17. ChristineToTheRescue

y=-2x+16?

18. CalebBeavers

correct

19. Mertsj

How can that be right when the slope of the given line is 1/4 and so the slope of the perpendicular is -4???

20. CalebBeavers

She said that was a typo, changed it to 1/2

21. CalebBeavers

So you're done. answer is y=-2x+16
