    y=-2x+3

    Step-by-step explanation:

    Slope intercept form is y = mx + b where m is the slope, b is the y-intercept, and y and x are their respective coordinates.

    The questions gives us a coordinate pair and a slope so all we need to find is the y-intercept to find the equation.

    Begin by plugging in what we know.

    (3) = (-2) (0) + b

    3 = 0 + b

    3 = b

    Plug in the y-intercept (b) and slope (m)

    y=-2x+3
