Start with the point (2, 3) and then reflect it across the x-axis, and then apply a dilation by 3 with respect to the origin to this new point. What is the final image coordinate.



Answer :

starting point = (2,3)

Any coordinate point (x,y) reflected across the y axis is equal to (x,-y)

So, the refection is equal to (2,-3)

Then, apply a dilation by 3, multiply each coordinate point by 3:

2*3, -3*3

Final image coordinate = (6,-9)
