If 2 lines are parallel, their slopes have to be
equal.
We'll put the given equation of the line in the
point slope form.
y = mx +
n
For this reason, we'll have to isolate y to the left side
and we'll add 4x and subtract 2 both sides:
2y = 4x -
2
We'll divide by 2:
y = 2x -
1
Comparing, we'll get the slope of the first line: m1 =
2
The slope of the parallel line is m2 =
2.
The line is passing through the point (-3 , 4). The
equation of the parallel line is:
y - 4 = 2(x +
3)
We'll add 4:
y = 2(x + 3) +
4
We'll remove the brackets:
y
= 2x + 6 + 4
We'll combine like
terms:
y = 2x +
10
The equation of the parallel line is:
y = 2x +
10
