I tried to learn the concept from this video months ago and I swear he made me scared.WHY DOES HE MAKE IT SOUND SO DIFFICULT???This whole lecture is based on the point-slope equation which is really just the slope formula anyway. How do you get slope m?(y_2 - y_1)/(x_2 - x_1) = m --> SlopeThen, get the x's over to the my - y_1 = m(x - x_1)  --> point-slope equationThen, we solve for y,y = m(x - x_0) + y_0 --> LinearizationHe makes it seem as if the eq comes out of thin air.. :o####[['NULL', 'Instructor', 'NEG']]
