    Answer:

    y = -2x + 4

    Step-by-step explanation:

    slope intercept form:

    y = mx + b

    m = slope = -2

    b = y-intercept

    x = x = 3

    y = y = -2

    Plug in the corresponding numbers to the corresponding variables:

    -2 = (-2) * (3) + b

    Simplify. First, multiply:

    -2 = (-6) + b

    Next, isolate the b. Note the equal sign, what you do to one side, you do to the other. Add 6 to both sides of the equation:

    -2 (+6) = -6 (+6) + b

    b = -2 + 6

    b = 4

    Plug in 4 for b in the equation:

    y = mx + b

    y = -2x + 4
