The slope of y=2x+1 is: 2. The parallel line needs to have the same slope of 2. We can solve it using the point-slope equation of a line: y â y1 = 2(x â x1) And then put in the point (5,4): y â 4 = 2(x â 5) And that answer is OK, but let's also put it in y = mx + b form: y â 4 = 2x â 10.
1 In-office teeth whitening treatments by a dentist can cost $300-$1,000 or more, but average about $500-$700.
Best Answer: It's $450 at the office I work at. That's for the tray, at home bleaching kit, and a few appointments to check progress. We also have a $250 new patient special. Stay away from the professional teeth whitening procedures and from the whitening at home kits.
