Exponents are hard but think about it like addition, that number tells you how many times to add that number to itself. To write the equation put the number and then the exponent on the top right of that number. Your welcome!
I'll test point P (0,-4) with its reflection point (4,-5). We see that x increased by 4 and y decreased by 1. Then we see that is reflected over some y value.
So the answer is (d) (the last one).
If n is 2 than fill in 2 for the n's
5+2=7
2- 1=1
7÷1=7
