Question

the coordinate p (-2, 7) is reflected over the y - axis. state the coordinate of p. (1 point)

o p(-2,-7)

o p(2,7)

o p(7,2)

o p(2,-7)

Explanation:

Step1: Recall reflection rule

When a point $(x,y)$ is reflected over the y - axis, the rule is $(x,y)\to(-x,y)$.

Step2: Apply the rule

Given point $P(-2,7)$, here $x = - 2$ and $y = 7$. After reflection over the y - axis, $x$ becomes $-(-2)=2$ and $y$ remains $7$. So the new point $P'$ is $(2,7)$.

Answer:

B. $P'(2,7)$
