Step 1:
First, we need to find the point (6, 8) on the graph.
We draw a point at the intersection of x = 6 and y = 8
Step 2:
From this point, we move 5 units to the left.
Graphically:
As you can see from the figure, we started at the point (6, 8) (marked in red)
Then we moved 5 units to the left and we end up at the point (1, 8) (marked in green)
