Question

Select the equation of the line that passes through the point (–2, 1) and has slope 3 in point-slope form.

A. (y + 1) = 3(x – 2)

B. (y – 1) = 3(x + 2)

C. (x + 2) = 3(y – 1)

D. (x – 2) = 3(y + 1)

Answer 1

basically, all you need is \[(y-(y intercept))=m(x-(x intercept))\] where m is the slope.

Answer 2

Ive been working on this for and hour now i still cant get it! I would really appreiate it if you would just tell me.

Answer 3

y intercept is y=1
x intercept is x=-2
m is slope m =3
plug that in to the equation I just gave you and
VOILA.

Answer 4

what?

Answer 5

hwo do i plug t in?

Answer 6

y=mx+b
1=3(-2)+b

Solve for b, which will give you your y-intercept. :o)

Answer 7

@Butterfly16 look at the answer format.
@Cookie_009 there is no t

Answer 8

Can you just plzzzzz tell me or show me how to plug it in?

Answer 9

REPLACE yintercept with 1 and xintercept with -2 and m with 3!! I don't think that's too difficult.

Answer 10

slope-point form:
Point Slope form: y-y1=m(x-x1)
Point Slope Form: y-1=3(x+2)

Does that make sense?

Answer 11

Im gonna kill myself!!!!!!!!!!!!

Answer 12

@Butterfly16 just gave the answer -_-

Answer 13

Is it a b or c or d

Answer 14

y-1=3(x+2)
Match it yourself.
