Question

Write an equation of a line that is parallel to the line y = -4x - 5? Perpendicular?
If you answer correctly, I'll select as best response and fan if not already.

Answer 1

parallel lines will have the same slope but different y intercepts
In y = mx + b form, the slope is in the m position and the y intercept is in the b position.

y = -4x - 5
parallel line to this is : y = -4x + 5 (or any other number besides -5)

perpendicular lines have negative reciprocal slopes. All that means is " flip " the slope over and change the sign.
y = -4x - 5.....slope is -4.....flip it and change the sign to find negative reciprocal. So you negative reciprocal of -4 is 1/4 (see how I flipped the slope and changed the sign)
So a perpendicular line to this could be : y = 1/4x - 5

any questions ?

Answer 2

no thnx :D it makes way more sense when u say it than when my teacher taught me it.
