To rotate a point 90 degrees counterclockwise, we can use the formula:
NewPoint(x, y) = (-y, x)
Applying this formula to the given point (-7, 4):
NewPoint(x, y) = (-4, -7)
Therefore, the new point after rotating the figure 90° counterclockwise is (-4, -7).
Given a point (-7,4) on a geometric figure what is a Newpoint after rotating the figure 90° counterclockwise
