Question

If ΔABC is reflected across the y axis what are the coordinates of C?

Answer 1

Answer:

D

Step-by-step explanation:

The reflection across the y-axis has the rule:

(x,y)→(-x,y).

So, the vertices of the triangle ABC after reflection across the y-axis will have coordinates:

• A(1,3)→A'(-1,3);
• B(3,6)→B'(-3,6);
• C(5,3)→C'(-5,3).

Hence, correct option is D

Answer 2

Answer:

d (-5,3)

Step-by-step explanation:

just flip it over to the other side.
