Question 486928: without graphing, determine whether the following pairs of lines are (a) parallel, (b) perpendicular, or (c) neither parallel or perpendicular:
5x - 6y = 19
6x + 5y = -30 Answer by John10(297) (Show Source):
You can put this solution on YOUR website! Solve for each line (for y) to find the slope. Then compare the slope
If two slopes are the same, the lines are PARALLEL
If the slopes PRODUCT is -1, two lines are PERPENDICULAR
Otherwise, neither parallel nor perpendicular.
