Question

a fish was plotted on a coordinate plane. identify the coordinates of the image of y that would create a - 270 - degree rotation about the origin. (1 point) o y(1, - 9) o y(-1, 9) o y(1, 9) o y(-9, 1)

Explanation:

Step1: Recall rotation rule

A - 270 - degree rotation about the origin is equivalent to a 90 - degree clockwise rotation. The rule for a 90 - degree clockwise rotation of a point $(x,y)$ about the origin is $(x,y)\to(y, - x)$.

Step2: Identify original coordinates

From the graph, the coordinates of point $Y$ are $(-9,-1)$.

Step3: Apply rotation rule

Using the rule $(x,y)\to(y, - x)$ with $x=-9$ and $y = - 1$, we get $(-9,-1)\to(-1,9)$.

Answer:

$Y'(-1,9)$
