Unit 6, Lesson 2# Interpreting Rate of Change and Initial Value

EngageNY 45 min(s)

Students interpret the constant rate of change and initial value of a line in context. Students interpret slope as rate of change and relate slope to the steepness of a line and the sign of the slope, indicating that a linear function is increasing if the slope is positive and decreasing if the slope is negative. They specifically interpret the slope of a linear function as a rate of change. Students also explain whether the rate of change of a linear function is increasing or decreasing.
