Whats the question
Answer:
y = x + 5
Step-by-step explanation:
The line passes through points (-7,-2) and (2,7)
Slope of the line = change in y ÷ change in x =
= 1
Taking another point (x,y) on the line;
Slope =
= 1
Cross multiplying this gives;
y - 7 = x - 2
y = x + 5
This is fairly simple. You would just substitute the answer choices in for 'n'.
3^-243=0
So, A. isn't correct.
3^-27=1.31137265.....
So, B. isn't correct.
3^-4=0.123456789 In fraction form this is 1/81
So, we think C. is the correct answer, but just to be sure, let's try D.
3^4=81 In fraction form this would be 81/1.
So, C. is our answer.
Hope this helps!!
