What's on the worksheet

  1. Decide if each equation describes a linear function and write it as y = mx + b:
    3y = 6x - 15y = \dfrac{12}{3x}y = \dfrac{3x}{12}y - 2 = 3(x + 1)y = 2x + 2^3
  2. Decide if each graph given by a list of dots is linear, nonlinear or not a function.
  3. Multiply out and simplify two rules and decide which one is linear.
  4. Word problem: the number of white tiles around Mei's square pools.
  5. Check Lucas's claim about equal steps for a rule with x cubed.
  6. Write a rule for each situation and decide if it is a linear function.
