Question

Rewrite the following expressions in x=my + b form.
a. 3x + 6y + 9 = 0
b. -2x + 6y - 4 = 0
c. -4x - 2y = 0

Answer 1

Set everything equal to x, then you'll get it to x=my + b

Answer 2

umm..I don't get what you mean! sorry

Answer 3

I'll start the first one for you

Answer 4

a. Subtract 9 from both sides so that you get:

3x+6y= -9
Then subtract 6y from both sides to get:

3x= -9-6y

Then divide by 3 on both sides to get:

x= (-9-6y)/3

Since 9 and 6 can be divided by 3,

x= -3-2y

Answer 5

to move everything from the left side to the right side, you need to either add/subtract from both sides

Answer 6

since you need it in x= my+b, (a) should look like this:

x = -2y-3
