One equation for this would be
We start by finding the slope between the two points:
A line parallel to this one will have the same slope. We will use point-slope form to write our equation:

<h3>Answer: Bottom left corner (southwest corner)</h3>
The left endpoint is x = 4, but we don't include this endpoint because of the open hole. We use a parenthesis to indicate "don't include the endpoint"
The right endpoint is positive infinity. We always use a parenthesis with either infinity since we cannot reach infinity
The interval from 4 to infinity is written as which is like saying
