Answer:
y=7
Step-by-step explanation:
Parallel lines have the same slope(m) value.
Since our line is parallel to one whose equation is y=4;
The slope of our line is hence zero.
Slope(m) = change in y ÷ change in x
0 = [tex]\frac{y - 7}{x - 0}[/tex]
Cross multiplying gives that the equation of our line is;
y=7
