Answer:
y = - 2x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (0, - 2) ← 2 points on the line
m = [tex]\frac{-2-4}{0+3}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2
• Parallel lines have equal slopes, hence slope of parallel line = - 2, thus
y = - 2x + c ← partial equation of parallel line
To find c substitute (- 5, 2) into the partial equation
2 = 10 + c ⇒ c = 2 - 10 = - 8
y = - 2x - 8 ← equation of parallel line
