```Hi,
I have a new (for me) situation.
I have a function for one linear model:
y = 9.7909-0.035*x
I have the variance of system
var = 13.01403
Is possible to create a random vector points of Y (simulating the real data)
over this curve using the function and the variance? I need this to a
discipline.

I have this:

| \
|  \ -> y = 9.7909-0.035*x and var =  13.014
|   \
|    \
|     \
|      \
|__________

I need something like this (generate this points):

|* \*
| * \**
|  **\ *
|    *\ **
|    * \*
|     * \ *
|       *\
|____________

Thanks for all
Ronaldo
