Standard(s) Taught

#### Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously.

Learning Targets and Learning Criteria

Students are successful when they can…

• construct straight trend lines to approximate the linear relationship between the plotted points of two data sets.
• justify the reliability of the trend line by noting the closeness of the data points to the line.
• understand that the trend line does not have to be proportional.
• determine the equation of the trend line that approximates the linear relationship between the plotted points of two data sets.
• interpret the y-intercept and slope of the equation in the context of the collected data.
• use the equation of the trend line to summarize the given data and make predictions regarding additional data points.
• graph a system of linear equations.
• identify the points of intersection as a solution to a system of linear equations.
• define the solution to a linear system of equations of equations as the intersection point on a graph.
