The coordinates of the image (9, -8) after a rotation of 90° counter-clockwise about the origin.

What is a graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

What is a scale image?

Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions on the actual figure or object

A rotation of 90° counter-clockwise about the origin is defined as the x-coordinate and y-coordinate change places, and the line y = x is the coordinates (-x , y).

To determine the image of the point (-9, -8) after a rotation of 90° counterclockwise about the origin

Suppose, the coordinates are (a,b)

A point (a,b) reflected across the line y = -x will become (-a,b).

Let a = -9 and b = -8

Substitute the values of a and b,

So the coordinates of image (9, -8)

Hence, the coordinates of the image (9, -8) after a rotation of 90° counter-clockwise about the origin.


The probable question can be: What is the image of the point (-9, -8) after a rotation of 90° counterclockwise

about the origin?
