Answer:
1 1/14 lbs
Step-by-step explanation:
We can use ratios to solve
2/3 crate 1 crate
----------------- = -----------------
5/7 lb x lbs
Using cross products
2/3x = 5/7 *1
Multiply each side by 3/2
3/2 * 2/3 x = 3/2 * 5/7
x = 15/14
x = 1 1/14
Simply plug in the points (-1,-4) into the equations, and B is the only one that holds.
