CCSS Description: Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.
Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data.
Throughout this worksheet students will focus on calculating slope of 10 straight lines shown on x and y axes.
The straight lines have both positive and negative slopes, four of which are fractional.
