Question

Triangle ABC has vertices located at A(1, -4), B(4, -6) and C(2, -1) on a coordinate grid. After it is reflected across the y-axis and a dilation of ½ is applied, what is the new coordinate of B? A. (4,6) B. (8,12) C. (2,3) D (-2, -3)

Answer:Step-by-step explanation:Givenreflection across y

RequiredNew coordinate of B

When reflected across the y-axis.The rule is:

So:Next is a dilation by 1/2

To do this, we multiply the new point by 1/2So:
