hint: solve for y

y=0?

-3?

how are you getting that

Never mind. That doesn't make since.

I really don't know..

I couldn't tell you. Sorry I suck at math.

compare
`5x+10y = 20`
to
`5x+10y-5x = 20-5x`
what's different?

-?

subtracting what

2?

hopefully you see the 5x being subtracted? or no?

I do!

ok so go back to the original `2x-2y = 6`
what do we do first?

Dont know.

maybe it might help to think of it as 0+2x-2y = 6

we have to undo that +2x

My laptop is almost dead.. Is there a faster way to find the answer?

we can come back to this later. Don't worry

but I need to get this done tonight..

subtract 2x from both sides
|dw:1443502454375:dw|

|dw:1443502471573:dw|

So the answer won't be negative?

so 2x - 2y = 6 turns into y = x-3 after we isolate y

compare `y = 1x-3` to `y = mx+b`
m = slope
b = y-intercept

Ok!

So is the answer -3?

|dw:1443503045153:dw|

|dw:1443503058099:dw|

|dw:1443503073175:dw|

1 is the answer?

yeah the slope is 1

-3 would be the y intercept
