Chapter 7 Student Learning Objectives SLO 7.1: I can make and interpret scatter plots to investigate patterns of association between two quantities. I can describe the patterns with strength words, clustering, outliers, positive or negative association, linear and nonlinear association. SLO 7.2: For scatter plots I can informally fit a straight line (“line of best fit”), and informally assess the model fit by judging the closeness of the data points to the line. SLO 7.3: Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed. SLO 7.4: I can use a triangle to explain the slope m from any two distinct points on a non-vertical line in the coordinate plane; and I can derive the equation y = mx + b for a line intercepting the vertical axis at b.
