Pre-unit diagnostic assessment

Assess students’ ability to
• identify functions and non-functions (8.F.A.1);
• identify linear and nonlinear functions (8.F.A.3);
• write an equation for the corresponding linear function when given two points on a line (8.F.B.4);
• find and interpret the rate of change when given a linear function that models a situation (8.F.B.4);
• interpret the graph of a function in terms of the situation it models (8.F.B.4).
