Given a point (−5, 4) on a geometric figure, what is the new point after rotating the figure 90 degrees counterclockwise??
To rotate a point 90 degrees counterclockwise, we can use the formula (x', y') = (-y, x), where (x, y) is the original point and (x', y') is the new point.
Using this formula, we can find the new point after rotating (-5, 4) 90 degrees counterclockwise:
x' = -y = -4 = -4
y' = x = -5 = -5
Therefore, the new point after rotating (-5, 4) 90 degrees counterclockwise is (-4, -5).
