Equation of a line in point-slope form (KristaKingMath)

► My Precalculus course: www.kristaking...
Learn how to use the formula for the equation of the line in point-slope form to find the equation of the line given various pieces of information about the line, including a slope and a y-intercept, a slope and a point, two points, or a point and the fact that the line is parallel to another line.

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.
