In this video we'll learn how to find the value of 'a' that makes two tangent lines of a function parallel to one another, assuming that the tangent lines intersect the graph at the points x=a and x=a+1.
Our approach will be to write equations for the tangent lines at these points, then simplify them into slope-intercept form in order to identify the slopes of each of them. Since parallel lines have equal slopes, we'll set the slopes equal to one another to solve for the value that makes them parallel.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)
Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”
So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
