Answer:
The answer to your question is y = 2x + 1
Explanation:
Data
line y = 2x + 3
point (-2, -1)
line parallel = ?
Process
1.- Find the slope of the original line.
The slope is the coefficient of the x, then the slope is 2
 y = 2x + 3
2.- Find the equation of the parallel line using the point slope equation
 y - y1 = m(x - x1)
-Substitution
 y + 1 = 2(x + 2)
-Simplification
 y + 1 = 2x + 2
 y = 2x + 2 - 1
-Result
 y = 2x + 1
