Learning Goal: Put linear functions altogether with an engaging and challenging Desmos task.

Classwork:

• Marbleslides: Lines (Desmos)

Standards:

• Common Core
  • HSF.BF.A.1 – Write a function that describes a relationship between two quantities.
  • HSF.IF.C.7 – Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases.
• TEKS (2015-16)
  • A.2(B) – write linear equations in two variables in various forms, including y = mx + b, Ax + By = C, and y – y1 = m(x – x1), given one point and the slope and given two points
  • A.2(C) – write linear equations in two variables given a table of values, a graph, and a verbal description
  • A.3(C) – graph linear functions on the coordinate plane and identify key features, including x-intercept, y-intercept, zeros, and slope, in mathematical and real-world problems
