Question

Again can someone explain in steps how to do this?

Without graphing,determine whether the following pairs of lines are (a)parallel (b)perpendicular, or (c) neither parallel nor perpendicular

5x-6y=19
6x+5y=-30

Answer 1

express the two equations like this y=ax+b
(a and b are just numbers)
the slope of the line will be: a
if they are the same than they are parallel
if they are the same with different signs (+-) than they are perpendicular
if they are completely different than there is no connection

Answer 2

there perpendicular maddie :)
