Question

How do you write an equation in slope-intercept form for(-2,1); m=1

Answer 1

Plug it into the equation:
(y-y1) = m (x-x1)
as (-2,1) = (x1,y1)
and m = 1

Answer 2

you're just getting people to do your homework, this question is the exact same as the last one you asked. You know these people won't be here when it comes test time

Answer 3

Can you solve that for me Mira? I can guide you through.

Answer 4

okay so, 1= 1(-2) +b right?

Answer 5

(y- 1) = 1 (x- (-2)
y - 1 = 1 (x + 2)
y - 1 = 1x + 2
y = 1x +1

Answer 6

wait what D: I'm so confused.

Answer 7

Haha, okay lets take it step by step.

Answer 8

The equation we plug these in is:
(y -y1) = m (x-x1)

The given points are:
(-2, 1) which substitutes as (x1,y1)

If we put it all together, we get:
(y - 1) = m (x - (-2)
Understood?

Answer 9

Yes okay..

Answer 10

equation is y=mx+b << u have (-2,1), which is x=-2, y=1, and m=1.... plug back in--- 1=1(-2)+b, solve for b, u get b=3, then rewrite, y=1x+3

Answer 11

Now lets plug in for m as well, giving us:
(y - 1) = 1 (x - (-2)

Answer 12

(y- 1) = 1 (x + 2) is what it becomes when simplified.

Answer 13

yeah so 1=1x-2?

Answer 14

im not following ur way, katrina..... u lost me lol

Answer 15

First: You forgot about the "y" before 1 = 1x - 2

Answer 16

Second: Its y - 1 = 1x + 2

(1x PLUS 2)

Answer 17

(y- 1) = 1 (x- (-2)
y - 1 = 1 (x + 2)
y - 1 = 1x + 2 <<<sign error
y = 1x +1 << should be y=1x+3?

Answer 18

Lol Yep.

Answer 19

got cha, i think the equation y=mx+b is way easier to remember

Answer 20

Hmm, but you have to begin with :
(y-y1) = m (x-x1)

Answer 21

OH I UNDERSTAND THANK YOU!!!!!!
