Answer:
y = – 2x – 13
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 )
y = – 2x – 5 ← is in slope- intercept form
with slope m = – 2
Parallel lines have equal slopes, thus
y = – 2x + c ← is the partial equation
To find c substitute (- 4, – 5) into the partial equation
– 5 = 8 + c ⇒ c = – 5 – 8 = – 13
y = – 2x – 13 ← equation of parallel line
