MCC8.SP.1 , MCC8.SP.2 , MCC8.SP.3 , MCC8.SP.4 I can write the equation of a line (in the form y = mx + b) given a point and a slope, two points, a table, or the graph of the line. I can explain a real world situation from an equation, table, or graph (explain the rate of change/slope and the y-intercept in the context). (linear only) I can create the equation, table or graph for a real-life situation. (linear only) I can describe the relationships shown in a scatter-plot (identifying patterns such as I can describe a relationship as increasing or decreasing, linear or nonlinear, from an equation, table or graph. I can construct and interpret scatter plots. clustering, outliers, positive or negative association, linear association, and nonlinear association). I can sketch a line of best fit on a scatter plot I can justify the location of my line of best fit and explain why or why not a given line is a good fit.

Video #1 Take Notes Survey: the number of hours you watch TV *remember there are only 24 hours in a day the number of hours you study daily * be honest Graph the class data (based on 6 students) What type of correlation did you create? Explain (what does the graph say) Video #2 (Line of Best Fit) Work Session/Guided Practice Material Needed: Graph Board & Marker
