Question

25
the coordinates of point b are (3, 4). determine the coordinates of b after a reflection in the y-
axis. * (10 points)
(4, -3)
(-3, -4)
(3, -4)
(-3, 4)
26

Explanation:

Step1: Recall reflection rule

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

Step2: Apply the rule

Given point \(B(3,4)\), here \(x = 3\) and \(y=4\). Using the rule \((x,y)\to(-x,y)\), we substitute \(x = 3\) into \(-x\). So \(-x=-3\) and \(y = 4\) remains the same.

Answer:

\((-3,4)\) (the fourth option)
