## Patrick_Wright 2 years ago what is the slope intercept of the line passing thourgh(-5,-2) and to the line y=1/2x-2

1. Trillography

Slope Intercept formula: y=mx+b

2. Patrick_Wright

ik that obviously but idk to do with the points and the equation

3. Trillography

Well if you obviously knew that then you would of known that the m is 1/2 and the b is -2. Then -5 is x and -2 is why. You have to put them in Slope intercept form.

4. Patrick_Wright

ok i got 8?

5. CalebBeavers

i think your question is missing a word

6. Patrick_Wright

yea its parrel ot the line

7. CalebBeavers

Alright. you see the slope of y=1/2x-2 is 1/2, right?

8. Patrick_Wright

wait? how is it 1/2?

9. CalebBeavers

Slope intercept form y=mx+b m is the slope

10. Patrick_Wright

yes

11. zaynahf

First use Point-slope form:\[y - y _{1}= m ( x - x _{1})\] If its parallel, it has the same slope, so m will be 1/2 The points will be (-5,-2), where Y1= -2 and X1= -5 Just plug these in, and isolate the y term on the left side to get slope-intercept form.

12. Patrick_Wright

o ok lol i did then but then i solved it. i wasn't supposed to solve it?

13. Patrick_Wright

nevermind did the math wrong

14. zaynahf

Can you tell me what you get?

15. Patrick_Wright

i got -2=1/2+-2

16. Patrick_Wright

1/2x*

17. zaynahf

You need to keep the x and y in there, and twhen you plug in in, it should look like: \[y + 2 = 1/2 ( x +5)\]

18. Patrick_Wright

isn't that point slope form?

19. zaynahf

Yes, but in order to get to slope int form, you need to start here, and then change to slope int form

20. zaynahf

Can you distribute the right side out?

21. Patrick_Wright

yes 1/2x+2.5

22. zaynahf

Ok so now you have y + 2 = 1/2 x + 2.5 Now carry over the 2 to the right side

23. Patrick_Wright

y=1/2x+1/2

24. zaynahf

Thats the equation in slope int form

25. Patrick_Wright

o ok thank you that really helped for my geom. final

26. zaynahf

No problem
