Answer:
since the lines are parallel to each other
m1 = m2( their slopes are equal)
4x - 2y = 8
-2y = 8 -4x
-2y = -4x + 8
divide both sides by -2
y = 2x - 4
since y = mx + c
m = 2
using the formula
y -y1 = m(x - x1)
y - 1 = 2 (x -(-2))
y-1 =2 (x +2)
y -1 = 2x +4
y = 2x +4 +1
y= 2x + 5(equation of the line)
