Determine, through investigation, that the rate of change of a linear relation can be found by choosing any two points on the line that represents the relation, finding the vertical change between the points (i.e., the rise) and the horizontal change between the points (i.e., the run), and writing the ratio

Determine, through investigation, connections among the representations of a constant rate of change of a linear relation

Express a linear relation as an equation in two variables, using the rate of change and the initial value

Describe the meaning of the rate of change and the initial value for a linear relation arising from a realistic situation and describe a situation that could be modelled by a given linear equation
