    hello : answer B

    because : when x = - 2 y = - 2+1=-1

    B) y=x+1

    Step-by-step explanation:

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

    m = (-3 - (-1)) / (-4 - (-2))

    m = (-3+1) / (-4+2)

    m=-2/-2

    m=1

    y-y1=m (x-x1)

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

    y+1 = (x+2)

    y+1=x+2

    y=x+2-1

    y=x+1
