Question

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

Answer 1

Since the line is horizontal, the equation for it will take the form of y = [number].

The y-value for any given horizontal line will always be the same, since the y-value represents height, and a horizontal line is always the same height.

We are given the point (-1, -8).

The y-value (height) of this point is -8.

Therefore the equation for the line is y = -8
