Answer:
(1, 5)
Explanation:
Cartesian Coordinate and Transformation
A coordinate defined as point (x, y) is called Cartesian Coordinate. The x-coordinate represents right-left direction while the y-coordinate represents up-down direction.
Its transformation depends on how would you move the coordinate point. An example is if you start with (x, y) point and move to right 3 units, our new position will be at (x + 3, y).
Properties
Suppose we have point (x, y), if we move to right “a” units then the new point will be (x + a, y)
If we move (x, y) to left “a” units, our new point will be (x - a, y)
If we shift (x, y) up “a units”, you’ll get (x, y + a)
If we shift (x, y) down “a units”, we’ll have (x, y - a)
Solution
Suppose you start at (1, 8) and you move down 3 units, you can apply the transformation property to find your new position.
Since you move down, this means you are dealing with y-coordinate only so you’ll apply property of (x, y - a)
You’ll have (1, 8 - 3) which equals to (1, 5).
Hence, you’ll end at (1, 5).
