Author: Hector Soto
Description:
  • Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.
  • Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear.
