Videos, solutions, examples, and lessons to help Grade 8 students know that straight lines are widely used to model relationships between two quantitative variables. For scatter plots that suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line.
Common Core: 8.SP.2
Fitting a line to a scatter plot allows you to predict values that don't already have.
This is useful because the slope and y-intercept will allow you to create a linear function in the form y = mx + b.
