Hi, there--

THE PROBLEM:

(A)Graph y=-x-2 on a set of coordinate axes.
(B) On the same set of coordinate axes, graph y=x-2.
(C) Describe how the changes in the coefficient of x affect the graphs.

A SOLUTION:
(A)Graph y=-x-2 on a set of coordinate axes.

Here is the graph of the first equation:

graph%28+600%2C+400%2C+-10%2C+10%2C+-10%2C+10%2C+-x-2%29

(B) On the same set of coordinate axes, graph y=x-2.

Here are both equations on the same graph:

graph%28+600%2C+400%2C+-10%2C+10%2C+-10%2C+10%2C+-x-2%2C+x-2%29

(C) Describe how the changes in the coefficient of x affect the graphs.

This is a good question for you to work on for yourself. 
What do you notice? 
What is the same?
What is different? 
Can you work out which numbers cause the changes?

Here is a link for graphing any equation online:

You can experiment there if you like.
