MEDAL AND FAN
What is the equation of the line that passes through the points (-3, 2) and (-5, 8)?
A) 3x-y=-11
B) 3x+y=-7
C) 3x+y=5
D) x+3y=3

Answer 1

@misty1212 could you please help me with this one as well?

Answer 2

yes, slope we should find first

Answer 3

y-mx+b

Answer 4

-3?

Answer 5

we do \[\frac{8-2}{-5-(-3)}\] to find the slope

Answer 6

8-2/-5+3 which would be 6/-2 =3 correct?

Answer 7

-3 excuse me

Answer 8

it would be \(\frac{6}{-2}=-3\) yes

Answer 9

Alright what do we figure out next?

Answer 10

we can do \[y-y_1=m(x-x_1)\] with \(m=-3, x_1=-3,y_1=2\)

Answer 11

\[y-2=-3(x+3)\] if we substitute
then multiply
\[y-2=-3x-9\]

Answer 12

add 2 to both sides?

Answer 13

yeah, also \(3x\) to both sides

Answer 14

So 3x+y=-11 :3

Answer 15

no thats not an answer choice....

Answer 16

\(-9+2=-7\)

Answer 17

Oh! :D so it would be y+3x=-7 answer choice B :D

Answer 18

Thank you so much @misty1212 ! :3

Answer 19
