Question

Determine whether the graphs of the given equations are perpendicular, parallel, or neither.

y=4x - 2 & -x + 4y=0

Two lines with positive slopes are parallel.
a. always
b. sometimes
c. never

Two lines with the same slope and different y-intercepts are perpendicular.
a. always
b sometimes
c. never

Answer 1

y = 4x - 2
-x + 4y = 0.....4y = x ...y = 1/4x
answer is neither

2 lines with positive slopes are parallel.....SOMETIMES....they would have to have the exact same positive number to be parallel.

2 lines with same slope and different y int. r perpendicular....NEVER. Lines with same slope and different y int are parallel, not perpendicular
