## anonymous one year ago Choose the equation of the horizontal line that passes through the point (−2, −1). y = −1 y = −2 x = −2 x = −1

You need a horizontal line, so you need something like y = something. That something needs to go through the point x=-2 and y=-1. So if you had an equation y=-1, it would be horizontal and also pass through the point (-2,-1). Does that make sense?

So how exactly do I find the answer? Is there a formula? @ybarrap

What is y in the graph above?

5. ybarrap

|dw:1444007612444:dw| Do you see this?

The answer is x=-1 right? @ybarrap

Thanks for the help @ybarrap I turned in my test and got it wrong. :) thanks a lot.

x=-1 is a $$\bf vertical~ line$$ y=-1 is a horizontal line as I indicated in the graph above: |dw:1444008098949:dw|

Again - the answer to this question is y=-1
