Y=2x-2
The line crosses through the y-axis at -2 and the slope is 2/1 or 2.
Some numbers you must know automatically know, so my suggestion is either search up the number or if you divided keep it with the division as a fraction.
Steps:
1. Do a proportion
8000 pounds/4 tons= 7000 pounds/ x
2. Do 7,000 times 4 which equals 28,000
3. Do 28,000 divided by 8,000
4. Your answer is
3.5 tons
