Graphs can be used to represent functions.
See attachment for the graphs of: <em>y =x - 2, y = 0.4x - 2, y =-x - 2</em>
The function is given as: 
When k = 1,
We have:
----- substitution property of equations

So, the equation is:
when k = 1
When k = 0.4,
We have:
----- substitution property of equations

So, the equation is:
when k = 0.4
When k = -1,
We have:
----- substitution property of equations

So, the equation is:
when k = -1
