Question

quilting a quilter is planning out a quilt using the coordinate plane below. the block is rotated clockwise 270° about the origin and drawn again. what are the coordinates of b after the rotation on the coordinate plane. a(1,3) b(7,3) c(7, - 3) d(1, - 3)

Explanation:

Step1: Recall rotation rule

For a 270 - degree clock - wise rotation about the origin, the rule for a point $(x,y)$ is $(x,y)\to(y, - x)$.

Step2: Identify coordinates of B

The coordinates of point B are $(7,3)$.

Step3: Apply rotation rule

Using the rule $(x,y)\to(y, - x)$ for point B$(7,3)$, we substitute $x = 7$ and $y = 3$. So, $B'$ has coordinates $(3,-7)$.

Answer:

$(3,-7)$
