    y+3=-2(x+1) y+3=-2x+2 -3 -3 y=-2x... Thats where im stuck.

    To find the points so you can graph it, just plug 0 in for x or y: y+3=2(x+1) 0+3=2(x+1) 3=2x+1 2=2x 1=x Here's a point: (1, 0) y+3=2(x+1) y+3=2(0+1) y+3=2 y= -1 Heres another point: (0, -1) You can plug any number in for x or y to find the a point. :o)

    Also, is it 2(x+1) or -2(x+1)?

    Okay, then ignore that last comment lol. y+3=-2(x+1) 0+3=-2x-2 3=-2x-2 5=-2x -2.5=x (-2.5, 0) y+3=-2(0+1) y+3=-2 y=-5 (0, -5)

    You can do this and find a few different points and then you can graph them. :o)

    @MaeganR didn't word the question too well. She said "solve" as in put it in point intercept form: y=mx+b
