I think I could be letter C
No a sphere consisting of steel at some dimensions such as 3 ft^3 wouldn't weigh the same as a sphere of silicone at 3 ft^3
Y=2X
Looking at the line you can see that it is moving up from left to right, making it positive. So -2X and -12X are incorrect.
Next we can find the slope by putting rise over run. Chose a point on the line, I’ll use (2,4).
On this point we rise to 4 and run over to 2.
So for rise over run we have 4/2 which is 2.
So y=2x is correct.
I would say the answer is c
