    Answer:y = - 2x

    Step-by-step explanation:

    slope-intercept form is as follows

    y = mx + b

    You are given that the slope is - 2 and since the line passes through the origin, there is no y-intercept

    So you just plug in the slope

    y = - 2x + b

    And since there is no y-intercept, you can take that out.

    y = - 2x
