Question

Put the equation in slope-intercept form and identify the slope of the line. 3x + 9y = 12

Answer 1

Perfect! Want yo try to do it by yourself? ( y =ax + b)

Answer 2

D.) None of the Above

Answer 3

ok hang on

Answer 4

Remember, you're trying to make y by itself.

Answer 5

so is it B

Answer 6

If by B you mean -2/3 then no

Answer 7

yes that what I meant lol. Darn...

Answer 8

Already from the start you can see that they can be divided by 3.

Answer 9

So it becomes x + 3y = 4

Is it easier to solve now?

Answer 10

i got a decimal again when i 3/4

Answer 11

Wait, don't think of this yet. Bring your x over to the other side. What is the new equation now?

Answer 12

3y=4x?

Answer 13

You substract the x. Don't multiply.

Answer 14

You only multiply when something is divided. (ex: 1/x = 2 then it becomes 2x=1)

Answer 15

so its just 3y=4?

Answer 16

x-x+3y = 4-x

3y = 4-x

Answer 17

now what do you divide the whole equation by to make y by itself?

Answer 18

3?

Answer 19

Exactly!

Answer 20

Can you do it?

Answer 21

im kinda ify

Answer 22

ify?

Answer 23

not sure, thats what i meant by ify lol. sorry :P

Answer 24

3y = 4-x

4/3 =

-x/3 =

Answer 25

y = -1/3x +4/3

Answer 26

The slope is -1/3

Answer 27

i appreciate it!!
