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

Fitting Lines to Scatter Plots (8.SP.2)
- I can show how straight lines are used to model relationships between two quantitative variables.
- I can informally assess the model fit by judging the closeness
of the data points to
- I can fit a straight line within the plotted data.
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.
Modeling and interpreting bivariate measurement data (Common Core
In this lesson you will learn how to interpret scatter plots by
identifying the line of best fit.
