Define y = mx by identifying the coordinates (x, y) of a point and rise/run (m) for a linear equation plotted on a coordinate plane that passes through the origin.
Clarifications:

Essential Understandings

Concrete:

  • Identify parts of a line graph.
  • Graph a series of coordinates on a coordinate plane.
  • Identify the two coordinates of a point on a line graph.
  • Examine the values of the x variable or y variable to look for a pattern.
  • Count the distance up/down between two points on the coordinate plane (rise).
  • Count the distance to the right, between two points on the coordinate plane (run).
  • Use a template (rise/run) to determine the slope.
  • Recognize a positive or negative relationship between two points.
Representation:
  • Understand the following concepts, vocabulary, and symbols: coordinates, ordered pairs (x, y), intercept, grid, axis, point, proportion, line, slope.
  • Graph a series of coordinates on a graph.
  • Identify given coordinates (x, y) as a point on a graph.
  • Identify the intercept(s) on a graph.
  • Identify the slope using the equation.
  • Identify the slope using the graph.
  • Use the format to write an equation for a line.

Date Adopted or Revised: 07/14
Cluster: Understand the connections between proportional relationships, lines, and linear equations. (Major Cluster) : 

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
