Thanks so much for the College Algebra videos, make this stuff so much clearer than my

I got the same answer and wondered the same thing.

at 4:56 in the first problem, shouldn't it be y=2x+3 as the answer? Thanks for the great videos by the way!

Hey everyone, ignore my previous statement. SsgtMath just messaged me an explanation of why his answer's correct.
 "On the parallel lines video, you asked "Confirming y=2x+3 is the correct answer at 4:56". It is not. Make sure you distribute the 2 (the slope) into (x+1) and you'll get 2x+2. Then when you isolate the y, you final result should be y=2x+4"

Confirming y=2x+3 is the correct answer at 4:56
Edit: I was wrong, read my other post
