@FedPete, you’re actually not that far off and that kind of creative thinking is a powerful tool when it comes to understanding math.
If you consider a horizontal line on an ordinary x-y graph.
The formula for that is, y = 0x + c, which cancels down to y = c.
Now if you flip the axes (so y runs along the horizontal) and graph the exact same horizontal line on your new a y-x graph, then you have x = 0y + c, or x = c.
Finally, you can flip the axes back to the correct x-y orientation but keep the formula the same (x = c), and this converts it from a horizontal line to a vertical one.
So you’re right, it is a creative way to solve the problem and is still a solution based in math.
It’s just solve more geometrically than algebraically.
This just goes to show that there is always multiple ways to tackle problems in math and if you can think about problems differently then you may even come up with a solution that no one has ever thought of before!
