M6L1 Outcome: Students construct linear functions based on verbal descriptions of bivariate data.

M6L1 Notes A linear function can be used to model a linear relationship between two types of quantities. The graph of a linear function is a straight line. A linear function can be constructed using a rate of change and initial value.

M6L1 Notes It is an equation of a line in which the rate of change is the slope of the line describes how one quantity changes with respect to another quantity. The initial value is the y-intercept.

Review How do I find the slope or rate of change in a graph? How do I find the slope or rate of change in a table?(2 ways)
