1. ( -1,2) is the same as (x=-1, y=2)
Substitute in your equation
y=3x-2
2=3•(-1)-2
2=-5 this is NOT true so (-1,2) is not a solution for the equation y=3x-2
2. (0,-2)
9x-6=3y
9(0)-6=3•(-2)
-6=-6 this is true so ( 0, -2) is a solution for the given equation
600 meters
Cause if you find multiples of 30 (for meters of course) 6 goes into it 5 times, which a fraction for 20%=1/5. So if you multiply 6 by 5 you get 30. After you can just add 2 zeros to the equation and its the same thing, But Just in bigger numbers.
Feel free to correct anything wrong. I wouldn't mind changing the answer if its wrong. :)
