Answer:
Option c. (x, y) → (y , x)
Step-by-step explanation:
we know that
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places
Remember that each point of a reflected image is the same distance from the line of reflection as the corresponding point of the original figure
so
The rule of the reflection across the line y=x is
(x,y) → (y,x)
The answer is -7+19i because of the procedure used in math
Substituting m for 9
h(9) = 9^2 - 3*9
h(9) = 81 -27
h(9) = 54
Third option!
30x + 42 = 6(5x + 7) you can understand it now
