Answer:
Thus, in total, there are 24=16 ways to answer the four questions. Only one of these 16 sequences is correct. Assuming each of these 16 sequences is equally likely to occur (as would result from random guessing), the probability that all four questions are answered correctly is 1/16.
The answer to that is: -12f+6g
Hope this helps ;-)
2 points on the line are (0,-4) and (6,0)
slope Is thus 2,/3
y= 2/3 x - 4
Multiply by -1 each time to get the answer in the output
