Question

How do you solve and graph `p-6>=3`?

Answer 1

See explanatom

Explanation:

Treat the manipulation the same way you would a normal equation.

Add 6 to both sides

`color(green)(p-6color(red)(+6)" ">=" "3color(red)(+6))`

But -6+6=0

`p+0" ">= 9`

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I know that they use the variable p but you would plot this the same way as you would `y>=9`

So the graph represents the equivalent of all the values of `y` that are greater than or equal to 9 no matter what value of `x`

As the 'p' may take on the value of 9 you use a solid line.

Just for a moment, suppose `p` could not take on the value of 9 `(p>9)` then the line would need to be dotted to indicate this condition
