What is the y-coordinate of a'? (picture included)

y- coordinate 0f A' = 2

note that the coordinates of A(1, 2 ) and the centre of dilatation (4, 2) both have the same y- coordinate 2

This means they are both on the horizontal line y = 2

and so the y- coordinate of A' will also be 2

45

step-by-step explanation:

30+15

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
