## Icewinifredd 3 years ago Someone please help me out!! I need to figure this out as soon as possible! I don't get geometry! :( please? What is the slope-intercept form of the equation y-7= -5/2(x+4)?

1. Godsgirl

im good at geometry

2. Icewinifredd

3. Godsgirl

haha okay whats the answer they give u

4. Icewinifredd

There are four of them and in this one, my teacher circled the answer but i have to explain to him how to get to the answer and that's why i need to show work. I didn't get it right the first time. 1.) y-2=-5/2(x+2) 2.) y+7=-x+5/2 3.) y=-4/7+2 4.) y=-5/2x-3 my teacher says that the 4th one is correct, but how to i get the answer????? that's the confusing part.

5. Godsgirl

okay wait i need to see something real quick

6. Icewinifredd

ok

7. Godsgirl

i working it out on a paper so it might be a while sorry and what is the slop intercept form

8. Icewinifredd

slope intercept form is y=mx+b.

9. Godsgirl

okay first you need to write this in slope intercept for y-7=-5/2 (x+4)

10. Icewinifredd

okay. got that. is this is answer? I'm just really desperate. Today is teh last day before the semester ends so i wanna redo this test to get my grade up.

11. Godsgirl

this is not answer im working on it

12. Icewinifredd

okay. sorry

13. Godsgirl

then what you would do next is use the distributive property

14. Godsgirl

which mean u multiply everything in the parenthesis by -5/2

15. Godsgirl

you would get 5/2x and then -5/2 times 4 is 20/2

16. Godsgirl

then you take the 20/2 and divide it and you get 10

17. Icewinifredd

okay. got that so far.

18. Godsgirl

right now ur equation should look like y-7=-5/2x-10

19. Godsgirl

after tht u would subtract 7 from each side so ur answer would be y=-5/2x-3

20. Icewinifredd

omg! you're a mircale worker! Thanks so much!!! :) I'm starting to get it now!! God bless you 1000 times!

21. Godsgirl

haha ur welcome
