You start at (0, 8). You move down 7 units and right 8 units. Where do you end?
1 answer:
<h3>Answer: (8, 1)</h3>
========================================================
Explanation:
The "move down 7" means the y coordinate 8 becomes 8-7 = 1
We subtract 7 from the y coordinate.
The "move right 8 units" means we add 8 to the x coordinate to get 0+8 = 8
Therefore, the point (0,8) moves to (8, 1)
