Determine whether the lines through the pairs of points are parallel, perpendicular, or neither. 6x + 2y = 8 15x + 5y = 21

OpenStudy (anonymous):

parallel - slope is same perpendicular - slope is negative reciprocal else neither.

OpenStudy (anonymous):

so they are neither

OpenStudy (anonymous):

6x+2y = 8 would become y=-3x+4 15x+5y=21 would become-3x+(21/5) They have the same slope and different y intercepts so they would be parallel.
