    y = - 2x-7

    Step-by-step explanation:

    Start with the linear equation formula.

    y = mx+b

    identify what you already have.

    x = - 2 and y = - 3 m (slope) = - 2

    we are trying to find b, so plug in what you have.

    -3=-2 (-2) + b

    simplify.

    -3 = 4+b

    subtract 4 on both sides.

    -7 = b

    set up your equation without the x and y value.

    y = - 2x-7
