Choose the system of equations which matches the following graph:

3x − 6y = 12
9x − 18y = 36

3x + 6y = 12
9x + 18y = 36

3x − 6y = 12
9x + 18y = 36

3x + 6y = 12
9x − 18y = 36

Select the correct answer from each drop-down menu. rewrite the formula to find voltage. the formula for electrical power (p, in watts) is where v is the voltage in volts and r is the resistance in ohms. for a particular brand of water heater, r is 32 ohms and p is 0.5 watts. the formula to find v is , and the voltage at which the heater operates is volts.
