Answer:
Your teacher is correct.
Step-by-step explanation:
Common knowledge about coordinates:
The first number in a coordinate is the "x coordinate".
The second number is the "Y coordinate".
The X axis is the horizontal line.
The Y axis is the vertical line.
The origin is the middle of the two axis's.
For A, the x coordinate is -4. You go right on the horizontal line because it is a negative number. The y coordinate is 4, so you go up from -4 to 4 because it is a positive number. there, you'll get your coordinate (-4 , 4).
For B, because the x coordinate is 0, you don't move at all, and you stay on the x origin. The y coordinate is 6, so you go up from the origin to 6. There, you'll have (0, 6).
C is pretty self explanatory if you understand the concept.

Answer:
x²-16
Step-by-step explanation:
x²-16 =0
Add 16 to both sides
x²-16 + 16 = 0 + 16
Simplify
x²= 16
For x²=(fa) the solutions are x = √(fa), -√(fa)
X=√16 ,X= -√16
√16=4
-√16 = -4
x=4, x= -4
