multiple-choice question subtracting 1 to the y coordinate of the points moves the points up left right down

Explanation:

In a coordinate system, the y - coordinate determines the vertical position of a point. When we subtract 1 from the y - coordinate of a point \((x,y)\), the new point becomes \((x,y - 1)\). Since the y - value is decreasing, the point moves downwards. Moving up would involve adding to the y - coordinate, and moving left or right involves changing the x - coordinate (subtracting from x moves left, adding to x moves right).

Answer:

down (assuming there was a missing option 'down' as per the partial view, and based on the rule of coordinate transformation: decreasing y - coordinate moves the point down)
