Find the slope of the line passing through the points (9,-9) and (1,-1)

The slope is -1

Step-by-step explanation:

Slope formula:

In (9,-9):   9 is x1 and -9 is y1

In (1,-1):      1 is x2 and -1 is y2

m= y2-y1/x2-x2

m= -1+9/1-9

Which is 8/-8

Simplify:

-1

The slope is -1

Hope this helps!

-1

Step-by-step explanation:

To find slope, take the two points and find the RISE/RUN, which is y-y/x-x. Stay consistent with how you order the numbers. In this case, I'll do -1 -(-9) / 1 - 9. That will give you 8/-8, which when simplified gives you -1.

2700

Hi Beckettdebbie! How are u?

I hope I understood the problem well.

In that case, you must calculate the volume of the small box and the volume of the large box and then make the division to see how many of the small ones enter the large one. Here the step by step:

Volume (large box) = 3,75 ft * 3 ft * 3,75 ft = 42,1875 ft^3

Volume (small box) = 0,25 ft * 0,25 ft * 0,25 ft = 0,015625 ft^3

Then, we calculate the number of small boxes that enter a large:

Amount small boxes = Volume (large box)/ Volume (small box)

Amount small boxes = 42,1875 ft^3/ 0,015625 ft^3

Amount small boxes = 2700

I hope I've been helpful!
