Question

A line contains the points (–4, 5) and (3, –9). Write the equation of the line using point-slope form

Answer 1

\[y=mx+b, m=\frac{ y_2-y_1 }{ x_2-x_1 }\]

Answer 2

A. Y+2=-2(X-3)
B.Y+5=-2(X-4)
C.Y-3=-2(X+9)
D.Y-5=-2(X+4)

Answer 3

thus the slope is m=-9-5 / 3- -4=-14/7=-2
y=-2x+b
plug in one of the points, say 3,-9
-9=-6+b
b=-3
thus, y=-2x-3

Answer 4

no I need one of those

Answer 5

is it a

Answer 6

@P0sitr0n

Answer 7

\[y-y _{1}=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\left( x-x _{1} \right)\]

Answer 8

dude no

Answer 9

is a right

Answer 10

A. Y+2=-2(X-3)
B.Y+5=-2(X-4)
C.Y-3=-2(X+9)
D.Y-5=-2(X+4)

Answer 11

no

Answer 12

how

Answer 13

it has to be y-5 or y+9 on L.H.S

Answer 14

so b

Answer 15

or d

Answer 16

check which can be, not guess.

Answer 17

im canceling out

Answer 18

y-y1 means either y-5 or y+9 on L.H.S
x-x1 on R.H.S can be x+4 or x-3

Answer 19

ik yur job isnt to just give me the anwers but im tired and ive been working all day at 8am i was up working on this math stuff and im really tired of looking at math and i have another house and a half of math work so can yu cut me some

Answer 20

hour*

Answer 21

m=-2 as Mr. P0sitr0n calculated.
y-5=-2(x+4) matches it.

Answer 22

yu said it wasnt a

Answer 23

oh nvm thank you soo much

Answer 24

inA it is y+2
