What is the equation?

2 Answer

  • Answer:

    C

    Step-by-step explanation:

    Put it into slope form

    y=mx+b

    distribute the -3 from (y+1) = -3 (x-1)

    y+1 = -3x +3

    subtract the 1

    y=-3x +2


  • Answer:

    y+2 = -3(x-1)

    Step-by-step explanation:

    We take 2 points and we can find the slope

    (0,2) and (2,-4)

    m = (y2-y1)/ (x2-x1)

        = (-4-2)/(2-0)

        = -6/2

        = -3

    The slope is -3


    We can use point slope form to make an equation.  We want to use the point (1, -2)

    y-y1 = m(x-x1)

    y--2 = -3( x-1)

    y+2 = -3(x-1)
