Answer:

D

Explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate the slope of the given line using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 4) and (x₂, y₂ ) = (2, 2) ← 2 points on the line

m =
(2+4)/(2+2) =
(6)/(4) =
(3)/(2)

Parallel lines have equal slopes and using (a, b) = (- 3, 1), then

y - 1 =
(3)/(2)(x - (- 3)), that is

y - 1 =
(3)/(2)(x + 3) ← in point- slope form
