Question

given a point -7,4 on a geometric figure, what is the new point after rotating the fugure 90° counterclockwise

Answer 1

To rotate a point 90° counterclockwise, we can use the following formula:

New x-coordinate = -old y-coordinate
New y-coordinate = old x-coordinate

Given the point (-7,4), we can calculate the new point after rotating 90° counterclockwise:

New x-coordinate = -4 = -4
New y-coordinate = -7 = -7

Therefore, the new point after rotating the figure 90° counterclockwise is (-4, -7).
