Urgent Algebra Help Needed

Question

Tell whether the lines for each pair of equations are parallel, perpendicular, or neither. Y= -4x + 3. -2x + 8y

I forgot how to do this help please!!

Answer 1

The following rules should help you to complete your assignment:

1. When two equations have the same slope they are parallel
2. For example: y=2x+4 and y=2x -8
3. To identify if an equation is perpendicular, the slopes need to be a negative reciprocal
4. For example: y= 2x+4 and y= -1/2x +5 are perpendicular. The slope of the first equation was 2 so you need to flip it and add a negative.

I hope this helps.
