 Question 375101: I may have this one figured out. I will show you what I have so far. The question is Determine whether the graphs of each pair of lines are parallel. 2x+4 = y and 2y = 4x - 7. I worked them out as the first line being 2 for the slope and the second being -7/2. I think these lines are NOT parallel because the slopes are different for each. Thank you.
