Answer:
y = 2x + 4
Step-by-step explanation:
[tex]P=(-1,\,2)\quad\implies\quad x_p=-1\,,\quad y_p=2[/tex]
The slope-intercept form the equation of the line:
y = mx + b
Two lines are parallel if they hav the same slope, so
m = 2 ⇒ y = 2x + b
The line goes through P so: [tex]y_p=2x_p+b[/tex]
2 = 2(-1) + b
2 = -2 + b
b = 4
so it's the same line as given one:
y = 2x + 4
