Write an equation of the line that passes through (−4,−5) and is parallel to the line y=−4x−1.
1 answer:
Answer:
y = -4x -21
Step-by-step explanation:
Use slope intercept form:
y = mx + b
use slope from original line: y = -4x - 1 so slope is -4
use the given point (-4,-5) for the x and y values and solve for b
-5 = -4(-4) + b
-5 = 16 + b
-5 - 16 = b
-21 = b
substitute b value in slope intercept form
y = -4x - 21
