To find the distance, you need to subtract the second point from the first one. So:
0 - (-9) = 9 ( two minuses turn into a positive)
And
7 - (-5) = 12
So the difference between the points is 9 units on the x- axis and 12 on the y-axis.
Hope this helped and pls mark as brainliest!

That is a ratio. 7 x 3 = 21 and 13 x 3 = 39.
Answer:
4,800 loaves.
Step-by-step explanation:
Solve by utilizing ratios and cross-multiplication.
suppose you wanted the tank to hold 100 gallons of water and it was 50 gallons per cubic feet. How many cubic feet would you need? Obviously, 2 cubic feet. How did you get that?? Well, you divided 100 by 50 to get 2.
O.K., now, let's try YOUR problem. 225000 gallons and 7.5 gallons per cubic feet. How many cubic feet do you need? Must be 225,000/7.5 = 30,000 cubic feet
O.K., now we're half way there. we (should) know that the volume of a prism is
l x w x h. We now know the volume must also be 30,000
so l x w x h = 30000
100 x 20 x h = 30000
you should be able to take it from there.
Problem #2
We approach it the exact same way.
It's too hard as stated. Let's make up an easier problem.
suppose 1 gallon took up 5 cubic feet. If you had 10 cubic feet, how many gallons would you have?
well, clearly, you would have 2 gallons. How did you get it?
Now, how many cubic feet in the cylinder? Well you (should) know that the volume of a cylinder is:
Pi r^2h = 3.14 x 25^2 h = 1962.5 h
Now we have a bit of a problem. You didn't tell me how high the tank is. Let us say it is 10 feet.
So, the tank had 19,625 cubic feet.
Go back to the start of this problem and you will know what to do next.
