Question

distance in the coordinate plane
#11
p(3,7)
is reflected over the y - axis.
units
#11:coordinates after reflection:____*
(-3,7)

Explanation:

Step1: Recall the reflection rule over the y - axis

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

Step2: Apply the rule to the given point

For the point \(P(3,7)\), here \(x = 3\) and \(y=7\). Using the rule \((x,y)\to(-x,y)\), we substitute \(x = 3\) into \(-x\). So, \(-x=-3\) and \(y\) remains \(7\).

Answer:

\((- 3,7)\)
