The formula of a slope:

We have the points (look at the picture) (0, 1) and (-2, -2). Substitute:

33/20 as well as 1 and 13/20. First you look it up in the internet aka Google.
-2 (-30) - 3y = 42
60 - 3y = 42
-3y = -18
y = 6
Answer:
208
Step-by-step explanation:
First let's find out what each container weighs..
Blue = 4 x 103 = 412
Red = 102 x 2 = 204
Now, Let subtract Blue container by Red Container..
412-204=208
Hence, the blue container weighs 208 more than the red container.
