Question

Which ordered pair represents a reflection of the point (-3, 5) across the y-axis?

Answer 1

Answer:

(3, 5)

Step-by-step explanation:

Reflection across the y-axis is: $A(x,y)\rightarrow A'(-x,y)$

Applying the rule to (-3,5):

$(-3,5)\rightarrow(3,5)\\\text {Because: }\\-3 * -1 = 3\\5 * 1 = 5$

So, the reflected point should be (3,5).
