-9

Do you want to graph it? @buddhababy002

3. anonymous

no i dont need graph, just how to solve it.

4. anonymous

I think he has written solve the equation.. @saifoo.khan

5. saifoo.khan

@buddhababy002 , the equation is already solved and it's in standard form.

6. anonymous

Ha ha.. Solve for y @saifoo.khan

7. saifoo.khan

@waterineyes , please let me solve the problem. :)

8. anonymous

Are you finding any x there ??

9. anonymous

Carry on @saifoo.khan

@buddhababy002 : Solve this equation, make y the subject. This will help you to convert the line in slope-intercept form.

11. anonymous

you do not need to, just move 5 to the right side, and divide both sides by 4

12. saifoo.khan

lol, really?

13. anonymous

Subtract 5 both the sides: $4y = -31 - 5 \implies 4y = -36$ Divide by 4 now: $y = \frac{-36}{4} \implies y = -9$

@waterineyes : haha. ;)

15. anonymous

@saifoo.khan I think you are using your brain more than required.. Ha ha ha..

16. anonymous

so u subtract both sides by 5 cause it doesn't have the variable right?

17. anonymous

I subtract 5 because we want to make variable on one side and constant terms on other side..

18. saifoo.khan

@waterineyes , hahah right! im used to that "more brain using" method actually. LOLOLOL

19. anonymous

ah i see.. okay thank you.
