## sarver1995 3 years ago Enter in standard form the equation of the line passing through the given point and having the given slope. B(2, - 5), m = -2/3

1. saifoo.khan

Use the short formula.. y - y1 = m(x-x1) y - (-5) = -2/3 (x - 2)

2. saifoo.khan

Solve.

3. sarver1995

y+5 = 2/3x - 4/3

4. saifoo.khan

Correct.

5. saifoo.khan

Now bring that into standard form.

6. sarver1995

2/3 x - y = i am stuck

7. saifoo.khan

make y the subject first.

8. saifoo.khan

y = 2/3 x -4/3 - 5

9. sarver1995

y = -2/3 - 5

10. saifoo.khan

wrong.

11. sarver1995

not sure what answer is then

12. saifoo.khan

|dw:1343322191844:dw|Can you solve from here?

13. sarver1995

not sure sorry

14. GOODMAN

What is it that you do not understand so i can help you out?

15. GOODMAN

Lets start this over. Basically you have got your slope and your b, so you are pretty much set up.

16. sarver1995

he said y = 2x/3 - 19/3 you cant substract that correct

17. sarver1995

so it would be 2x/3 - y = -19/3

18. GOODMAN

y - y1 = m(x-x1) y - (-5) = -2/3 (x - 2) y+5=-2/3x + 4/3

19. sarver1995

okay i see that so far

20. sarver1995

then i understand the 2/3x - y = 4/3 - 5 after this is where i get confused

21. GOODMAN

From there, you must but it into standard form, having all the x's and y's on one side. Subtract y, and then subtract 4/3. Giving you 11/3=-2/3x-y

22. sarver1995

2/3x-y = 11/3

23. GOODMAN

Yes. Only dont forget the (-) sign in front of the 2/3

24. sarver1995

okay thanks

25. GOODMAN

np :)

26. sarver1995

in my problem it will not let me have / as an option

27. GOODMAN

Okay, then you can get rid of the fractions by multiply each side by 3.

28. GOODMAN

Giving you -2x-3y=11

29. sarver1995

thanks

30. GOODMAN

Sure.
