Answer: Plot the two points (3,-6) and (1, -5). Draw a straight line through those points.
See the graph below.
=============================================
Explanation:
Plot the point (3, -6)
The slope -1/2 means the rise is -1 and the run is 2
If we moved to the right, then we'd drop down 1 and move to the right 2. That would move us from (3,-6) to (5,-7)
We can go in reverse of this. So instead of "move down 1", we move up 1. We're going left instead of right.
-----------
So we start at (3,-6) and move up 1 and to the left 2 to arrive at (1,-5)
Two points on this line are (1, -5) and (3, -6)
Once we have two points, we have enough to graph the line.
See the graph below.
