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
