  6. quadrants: the two axes of a coordinate plane divide it into 4 sections called quadrants; top right= I top left= II bottom left= III bottom right= IV
  7. Rise means: the differnce between the y-coordinate values of the two points on the line
  8. Run means: the difference between the x coordinate values of the two points on the line
  9. Slope =: rise/run = change in y / change in x
