Answer 4

i did this 2 years ago, so im trying to think of a way to solve it

Answer 5

ok thank you

Answer 6

do you just need the equations of both lines or to solve the systems?

Answer 7

@thedomination100

Answer 8

it says this

Answer 9

ok i got the equations of the lines, do you think you can take it from there?

Answer 10

ok

Answer 11

so the equation of line 1 is: y=-3x+6
equation of line 2 is y=3x-1

Answer 12

so then, from there you just use the elimination method

Answer 13

i still dont get it

Answer 14

x=2, y=5

Answer 15

do you want me to explain how got it?

Answer 16

yes please

Answer 17

ok, so you find the slope of the first line, then you insert that value into the slope intercept form

Answer 18

so for the first one \[\frac{ -3-9 }{ 3-(-1) } = \frac{ -12 }{ 4}=-3\]

Answer 19

so -3 is your slope for the first line

Answer 20

then you use \[y=mx+b\] and insert a point and the slope

Answer 21

do you get it so far?

Answer 22

yes thank you

Answer 23

so then your equation would be \[9=-3(-1)+b\] and you solve for b

Answer 24

so then the slope intercept equation for the first line would be y=-3x+6

Answer 25

and you do the same thing or the other line

Answer 26

understand?

Answer 27

well i gotta go
