Represent data on two quantitative variables on a scatter plot, and 1. describe how the variables are related. a. Fit a function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear, quadratic, and exponential models. b. Informally assess the fit of a function by plotting and analyzing residuals. c. Fit a linear function for a scatter plot that suggests a linear association. MACC.912.S-ID.3.7 2. Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data. MACC.K12.MP.4.1, MACC.K12.MP.5.1, MACC.K12.MP.8.1 Also Asses Item Types This benchmark will be assessed using MC and FR items. Benchmark Clarification Students will graph data on a scatter plot, describe the association, and interpret the slope. Content Limits Data points limited to one, two, or three digits Stimulus Attributes Tables and charts may be used. Items may be set in either real-world or mathematical contexts. Response Attributes Equations may be presented in standard or slope-intercept form. * Teacher may assess in the classroom. SAMPLE ITEM Mrs. Santiago would like to know how well her Algebra students will perform on the state’s End-of-Course Assessment. She has decided to gather some data from the previous year in
