## countonme123 2 years ago Find the slope intercept form of each equation then graph each line. x + 3y = 6

i am totally confused on how to work these...

Hello, my name is Stephen and I'll be your tutor In the form: y = mx + b, m is the slope of the equation and b is the y-intersect You first want to put the equation in y = mx + b by solving for y. To do this, take x + 3y = 6, and subtract x, and then divide by 3.

3. countonme123

so now it is y= 2-x ???

4. Compassionate

x + 3y = 6 3y = 6 - x y = 2 - 3x y = 3x - 2

5. countonme123

ok now what?

6. Compassionate

Now, you go to -2 on your y-intersect and your slope is 3/1, so you rise 3 and run 1.

:( i am afraid i am confused

Draw a graph on a piece of paper for me. 10 high and 10 low.

9. countonme123

hmm ok got it

|dw:1371942073702:dw| Those black lines are your middle points. Now, on your y intersect go over -2 spaces

13. Compassionate

Now rise 3 and over 1

16. Compassionate

Correct! Now you've graphed the equation!

17. countonme123

yes

18. countonme123

i believe it was supposed to be what Shames wrote

19. Compassionate

Yup, it is.

20. Shames

you only went up 2

22. countonme123

@Shames i noticed after your post... thanks for catching me.

23. Shames

np

25. Compassionate

We just sovled that.

26. countonme123

i am not sure what to put though

27. countonme123

y = 3x - 2 is that it?

28. Shames

(1,1)

29. countonme123

That is the slope intercept form ?

30. Compassionate

Yes.

31. countonme123

ok thanks guys i will post one more

32. countonme123

you both helped alot thanks
