How do you graph #y=-2#?

Answer 1

Julia Adams

This is the equation of a horizontal line passing through the y-axis at -2

If you consider this equation in the form #y = mx+c#, then we see that #m=0#

This means that the line has a zero slope, so it is a horizontal line. The #y-#intercept is #-2#

Therefore this is the equation of a horizontal line passing through the y-axis at -2.

To graph ( y = -2 ), plot all points where the y-coordinate is -2. This creates a horizontal line parallel to the x-axis at y = -2.

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.
