Answer:
D
Step-by-step explanation:
2x + 5y = - 10 Subtract 2x from both sides
5y = -2x - 10 Divide by 5
y = -2x/5 - 10/5
y = 0.4x - 2
The slope is minus so the line is going from lower right to upper left as B and D are doing.
The y intercept is - 2. B goes through + 2 so it is not the answer.
The answer is D

Answer:
-4 to 3
Step-by-step explanation:
look at the first number in each set then find the smallest and the biggest that is how you find range
Answer:
-3
Step-by-step explanation:
To find the average of different numbers, first you add them all up. So -5+-7+-2+2+-3+=-15. Then, you divide the sum of all the numbers by the amount of numbers there were. So in this case, there were 5 numbers so we would divide the sum of all of them by 5. So now we do -15/5=-3.
Another example of finding the average of numbers is 15+4+10+9+3+1. So first we add them up and we get 42, then again, we divide by the amount of numbers there are. So we do 40/6 and we get 7, so the average is 7.
I hope this helped.
