Answer:
2x+y=4
Step-by-step explanation:
1) if the required line is parallel to the given one, it means, that the equation of the required line has 2x+y=C, where C - unknown number;
2) it is possible to calculate 'C', if to substitute the point (0;4) into the equation of the required line:
2*0+4=C; ⇒ C=4.
3) finally, the required equation is: 2x+y=4.
