Question

how do you put x - y = -1 in slope intercept form

Answer 1

Slope intercept form is \(\color{blue}{y=mx+b}\)
How would you get it to look like that?

Answer 2

idk

Answer 3

Well we need to get y alone on the left side of the equation, what would you do to achieve that?

Answer 4

subtract y from both sides???

Answer 5

I would subtract x from both sides first. Try that and tell me what you get :)

Answer 6

-x-y=1??

Answer 7

We have,

\(x-y=-1\)
Right?

Subtract x from both sides.

\((\cancel{x}-y)-\cancel{x}=-1-x\)
\(-y=-x-1\)

Answer 8

Now we need y not -y, so what would you do to both sides to do that? (Hint: this is easy)

Answer 9

divide by -y ?

Answer 10

Nope, negate both sides. Divide each side by negative 1.

Answer 11

how?

Answer 12

\(\dfrac{-y}{-1}=\dfrac{-1-x}{-1}\)

Answer 13

what should i get?

Answer 14

what is a number divided by one?

Answer 15

1

Answer 16

No, any number divided by one? What is it.

Answer 17

that number

Answer 18

Exactly, and what if that one is negative?

Answer 19

ooo i got it is the answer y= 1-x

Answer 20

????

Answer 21

\(\dfrac{-x}{-1}=~?\)

Answer 22

yes

Answer 23

No, what does it equal?
