Question

IS THE FOLLOWING PARALLEL, PERPENDICULAR, OR NEITHER?

-3Y = -4X + 4 -4Y = 3X + 5

Answer 1

Wow!!!! thank you.

Answer 2

-3y = -4x + 4
y = 4/3x - 4/3
slope = 4/3

-4y = 3x + 5
y = -3/4x - 5/4
slope = -3/4

Parallel lines will have the same slope.
Perpendicular lines will have negative reciprocal slopes...all that means is " flip " the slope and change the sign.
4/3...flip and change sign = -3/4....these lines are perpendicular
