Things to Learn

  • Associate with each ratio A:B the ordered pair (A, B) and plot it in the x–y coordinate plane.
  • Given a ratio table, plot the ratios in the plane and observe that they lie on a line through the origin.
  • Find that the coordinates in the line satisfy y=kx, where k is the value of an associated ratio.
