Please I need help to do this

Hey there! Hello!
For this problem, I'm assuming you need help figuring out what quadrants contain which positive and negative plot points, and I can certainly help with that.
I have attached a quick little drawing I did of the different quadrants' labels and their corresponding positive and negative numbers, if that makes any sense. Keep in mind that when you cross the y-axis (the vertical one) from the right to the left side, your x-value will be negative. Same goes for the y-value, except it will be positive on the top and negative on the bottom.
Hope this helped you out! Feel free to ask any additional questions if you have any, or if you still need help figuring out which point on your worksheet goes in which quadrant. :-)

Let and
be the number of elves and reindeers, respectively.
We know that:
(so far 14 of them have arrived)
(each reindeer has 4 legs and each elf has two)
If we multiply the first equation by 2 we have , and if we subtract this equation from the second we have
which implies
.
So, there are 5 reindeers and 9 elves (remember that they have to sum up to 14).
Answer: There is probability of 0.367 that there will be no breakdown on his car in the trip.
Step-by-step explanation:
Since we have given that
Mean (λ) = 0.5 breakdown per week
Number of weeks the owner of the car is planning to have a trip on his car for = 2 weeks
So, mean for 2 weeks would be
We need to find the probability that there will be no breakdown on his car in the trip.
Probability that there will be no breakdown on his car in the trip is given by
P(X=0) is given by
Hence, there is probability of 0.367 that there will be no breakdown on his car in the trip.
