Question

What is the image of (-8,10) when reflected in the y-axis

Answer 1

(8,10)

Explanation:

If we reflect a point over the y-axis, the x becomes opposite while the y stays the same.

So the rule here is (a,b)->(-a,b) if we are reflecting over y-axis.

So if you reflect (-8,10) over the y-axis you get (8,10).
