SOLUTION: Will someone please show me how to determine whether the lines: (x+1)/3 = (y-2)/2 = (x+7)/5 and (x-3)/-2 = (y+2)/-2 = (x-1)/2 are orthogonal, parallel, or neither. How is this don

Question 334424: Will someone please show me how to determine whether the lines:
(x+1)/3 = (y-2)/2 = (x+7)/5 and (x-3)/-2 = (y+2)/-2 = (x-1)/2 are orthogonal, parallel, or neither. How is this done?
Thanks,
-Nick.
Answer by Fombitz(32388) (Show Source): You can put this solution on YOUR website!
Convert the lines to slope intercept form, .
Then compare slopes.
Parallel lines have identical slopes,
Perpendicular lines have slopes that are negative reciprocals, .
All others fall into the neither category.

I couldn't make sense of your equations because they have two equals signs in them. ?
