You're going to be surprised at how important finding the equations of lines is in Calculus. In some chapters, you'll be doing it as the last step to almost every problem! So, let's make sure that you really have it down.
The standard form for the equation of a line is
But, the form that is used the most in Calculus is the slope-intercept form:
Slopes are going to be a big deal and this form shows the slope!
Let's do a quick review of the pieces and how the graphing works just to clean some cobwebs out of your brain.
Remember the pieces:
