Last chapter, we saw that you can graph a line provided that you know the starting point (a coordinate) and the slope (which allows you to find other coordinates).  If the starting point is the y-intercept of the line, then there is specific format called the slope intercept form:

y = mx + b

Things you should know after today:

  • the relationship between the equation of a line and each of the coordinates on the line
  • how to determine the slope and y-intercept from an equation in slope intercept form
  • write an equation in slope intercept form a graph or if you are given the slope and the y-intercept
