Slope of a Line
Identifying graphs that represent equations. Calculating unit rates when data is given in a verbal statement or a graph. Identifying graphs that represent a particular unit rate and using unit rates to evaluate proportionality. Determining the type of unit rate of change and calculating the same for word problems. Comparing the slopes of different lines on a graph and arriving at a conclusion. Identifying lines on a graph that have the same slope.
Mapped to CCSS Section# 8.EE.B.5
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.
