Rotate the point (-4, -6) on a geometric figure 90 degrees counterclockwise. What is the new point? (1 point)
A.(6, 4)
B.(6, -4)
C.(-6, -4)
D.(-6, 4)
To rotate a point 90 degrees counterclockwise, we can switch the x and y coordinates and negate the new x coordinate.
The original point is (-4, -6).
Switching the coordinates gives us (-6, -4).
Negating the x coordinate gives us (6, -4).
Therefore, the new point after rotating 90 degrees counterclockwise is B. (6, -4).
Rotate the point (9, 5) on a geometric figure 270 degrees clockwise. What is the new point? (1 point)
A.(-5, -9)
B.(5, 9)
C.(-5, 9)
D. (-9, -5)
To rotate a point 270 degrees clockwise, we can switch the x and y coordinates and negate the new y coordinate.
The original point is (9, 5).
Switching the coordinates gives us (5, 9).
Negating the y coordinate gives us (5, -9).
Therefore, the new point after rotating 270 degrees clockwise is (5, -9).
So, the correct answer is A.(-5, -9).
