What’s the line of y= -1/2x+2

Is a currency whose value is tied to another currency, meaning that the exchange is fixed

For what value of (y) is 3^3/3^y =1/9

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
