Learning Objectives
| Students need to be able to … | In order to … |
| Plot an ordered pair (x, y) in a rectangular coordinate system | Create scatterplots and residual plots |
| Use the equation of a line to find the y-value associated with a given x-value | Use the regression line to make predictions |
| Given the equation of a line, draw the graph of the line | Graph the regression line |
| Find the equation of a line from its graph | Understand and interpret regression coefficients in a data context |
| Understand the y-intercept as the value of y when x equals 0 | Interpret the y-intercept of the regression line or explain why it as no reasonable meaning |
| Find the vertical distance between a point and a line | Calculate residuals |
