Step 1:
First, let us find the point (4, 3) on the graph.
Mark the point at the intersection of x = 4 and y = 3
Step 2:
We are at the point (4, 3) now move down 3 units and mark the point
Step 3:
Finally, move up 1 unit and mark the point.
Graphically:
As you can see, we started at point (4, 3) (marked in blue)
Then we moved down by 3 units to the point (4, 0) (marked in green)
Finally, we moved up by 1 unit to the point (4, 1) (marked in red)
Therefore, we end up at the point (4, 1)
