    Answer:

    • A. -9

    Step-by-step explanation:

    Slope-intercept form:

    • y = mx + b

    If m = 0, then:

    • y = b

    Parallel lines have same slope, so line k has similar formula. Having  point (-1, -9) on this line, its equation will be:

    • y = -9

    So for any x-coordinate, this line has one value: -9 as y-coordinate

    Correct answer option: A. -9
