Question

Write the equation of the horizontal line passing through the point (-1, -8).

Answer 1

is that the whole question? or is there more to it?

Answer 2

Here the details:
1. Give the coordinates of two points on the line x = 5.
2. Give the coordinates of two points on the line y = -2.
3. Write the equation of the horizontal line passing through the point (-1, -8).
4. Write the equation of the vertical line passing through the point (3, 1).
5. Is the line with equation x = 4 horizontal or vertical? What is the slope of this line?
6. Is the line with equation y = -8 horizontal or vertical? What is the slope of this line?

For 1 I answered: (5, -6) and (5, 9)
And for 2 I answered: (7, -2) and (10, -2)
