Check my answer..? Write an equation of the line passing through the point (-4,2) and is parallel to y= -x+6 I got: y= -x+6; is it correct?

    Maybe y=-x-2 ?

    i had to use this equation: y-y1=m(x-x1)

    start with y=-x+c put the point (-4,2) there, and find c

    m=-1

    i think..?

    yes, because lines are parallel

    and (x1,y1) = ?

    (-4,2)

  15. Steph_Rawr352

    so it would be: y-2=-1(x-(-4)) right?

  16. hartnn

    so now just put the values in y-y1=m(x-x1)

    yes, that is correct

    ohk so then i would distribute? y-2=-1x+4 ?

    u missed the brackets...

  21. Steph_Rawr352

    no cuz i multiplied (x-(-4)) by -1

  22. hartnn
    • 2 years ago

    You've already chosen the best response.

    so u get -1(x+4) = -x-4

  23. hartnn

    -(-4) = +4

    ohh ohk so the answer would be y=-x+-2 or y=-x-2 ?
