## waheguru 2 years ago How do I convert y = 2/3 x - 7 to standard ax + by +c = 0 form

1. waheguru

*more so I do i get the = 0 part...??

2. mathstudent55

Since you have a denominator of 3, first multiply both sides by 3. Then add or subtract the terms on the right side to move them to the left side.

3. mathstudent55

y = 2/3 x - 7 Multiply both sides by 3: (3)y = (3)(2/3 x - 7) What do you get? Remember to distribute the 3 on the right side.

4. waheguru

so 3y = 2x -21

5. waheguru

what do i do from here?

6. mathstudent55

Now since you want everything on the left side, subtract 2x from both sides, and add 21 to both sides.

7. waheguru

can you please show the following steps

8. mathstudent55

3y = 2x - 21 -2x + 21 -2x + 21 -------------------------- -2x + 3y + 21 = 0 If you don't like to have a negative sign at the beginning (with the x term), you can multiply both sides by -1 and get 2x - 3y - 21 = 0

but i also saw a formula in standard from as 2x-3y = 12. would this be condisered stard from
