Answer:
1/-4
Step-by-step explanation:
slope = y2-y1/x2-x1
slope = 5-3/-3-5
Slope = 2/-8
Slope = 1/-4
4/5 would be 32/40 in simplest form.
To find the simplest form of 32/40 you would have to find the least common multiple of 32 and 40.
You can keep on adding until you find a common multiple.
32 64 96 128 160
40 80 120 160
After you find the least common multiple (160), you divide 32 and 40 by 160.
160÷32=5
160÷40=4
4 would be your numerator and 5 would be the denominator. So, you would get the fraction 4/5 as your answer.

Step-by-step explanation:
Answer:
260 eggs per person per year.
Step-by-step explanation:
We have been given that over the last 40 years, the percent decrease in egg consumption in the U.S. is 35%. Forty years ago, the average consumption was 400 eggs per person per year.
To find the average consumption of eggs today, we will find 65% (100%-35%) of 400.
Therefore, the average consumption of eggs today is 260 eggs per person per year.
