How do you write the equation of the horizontal line passing through (-8,9)?

Answer 1

#y = 9#

The equation of any horizontal line is #"y = .. a number"#

The x-value has no effect on the equation or on the line at all, as long as y-value stays the same.

In this case the line passes though the point #(-8,9)# which tells us that the y-value we want is 9.
Therefore the equation is #y = 9#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
