Blurry picture but i really need this answered this test is worth more then half my grade.

These are the coordinate pairs: (0,0), (2,4), (3,6), (6,12)

Step-by-step explanation:

since y=2x, you just multiply every value for x by 2, so for the x values 0, 2, 3, and 6, you would get 0, 4, 6, and 12, respectively.

At least in my country, that price includes the tax (and that tax is rather small, compared to that here, whatever)
so, 325 is the final price. the original is 325*100/(100+8), while the tax is 325*8/(100+8). you calculate them.
if the price is before the tax is applied, then the final price is 325*(100+8)/100, while the tax is 325*8/100.
