Answer:
It's all about the brackets.
Step-by-step explanation:
If we do (-4)^2, the brackets make it -4 x -4 and the two negatives make a positive of 16.
If we do -4^2, that means that the 4 is squared before putting the minus sign there so you have 4x4 = 16 then put the minus to get -16.
Hope this helps!

Answer:
Slope of equation x = 3 is not defined.
Step-by-step explanation:
The graph for equation
is attached.
As clear from the graph, x=3, is a straight line parallel to y-axis.
Slope:
- Since the given equation of line is parallel to the y-axis and parallel lines have same slope.
- Parallel lines have the same slope and will never intersect. Parallel lines continue, literally, forever without touching
Thus, the given equation will have the same slope as the y-axis.
The slope of y-axis is not defined.
Hence, the slope of this line is not defined.
