Answer:
B) Its final coordinates are (8,-6)
Step-by-step explanation:
1. Translated 1 unit up and 4 units left
(-2,7) becomes (-6, 8)
2. Reflected about the x-axis
(-6,8) becomes (-6, -8)
3. Rotated 90° anticlockwise about the origin
(-6, -8) becomes (8, -6) because when rotating 90 degrees anticlockwise about the origin, point A (x,y) becomes point A' (-y,x). In other words, switch the x and y and make y negative.
Answer:
see attached graph
Step-by-step explanation:
You graphs look fine. The only thing I can think of without seeing the question itself, its that perhaps the teacher wants them on the same graph?
I positive 15 and negative 15, in effect the absolute value function just removed negative signs
The area of a circle is pi times the radius squared (A = π r²).
