Question

Are these lines parallel y = -2x + 1 and y = -2x - 4

Answer 1

Answer:

The lines are parallel

Step-by-step explanation:

y = -2x+1 and y = -2x+4 are in the form y = mx +b

Both have a slope of -2

If the slopes are the same the lines are parallel

Answer 2

Answer:

YES

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

Parallel lines have the same slope.

We have:

$y=-2x+1\to m=-2\\\\y=-2x-4\to m=-2$

The slopes are the same. Therefore the lines are parallel.
