I'm homeschooled, and right now I'm on this unit. The books that I am using don't explain this well enough and the purplemath guide confused me.
Can somebody please work through a problem or help me please?
It is to be regretted that all the worked examples in your various books and in the online lesson(s) have left you still confused. But one more example, which would be worked the exact same way -- "the parallel line's slope is the same value" and "the perpendicular line's slope is the flip, with the opposite sign" -- is unlikely to fix whatever is the underlying problem. Sorry!...The books that I am using don't explain this well enough and the purplemath guide confused me. Can somebody please work through a problem or help me please?
