Question

Given a 90 counterclockwise rotation find tha image of -5,7

Answer 1

• The image of the point (-5,7) is the point (-7, -5)

Step-by-step explanation:

A 90 ° counterclockwise rotation is a rigid transformation that transforms any point (x,y) of a figure into a point with coordinates (-y,x).

The rule is:

• (x,y) → ( - y,x),

Where (x,y) represents the coordinates of the preimage (the original figure) and (-y,x) represents the coordinates of the image.

Using the rule with the point (-5,7) you get the image: (-7, -5).
