Coordinate PLANES: Paper Airplanes from Linear Equations

Graph, fold, and fly! If the students graph all the lines correctly, their worksheets will fold up into paper airplanes. Students get plenty of practice with graphing linear equations and using slope-intercept form.   This activity is a fun way for your class to practice using slope of a line and graphing lines using Slope-Intercept Form. One version also includes reflections of lines on the coordinate plane.   Students graph lines and complete a short worksheet, then follow the directions to fold along their lines to create a paper airplane.   Three versions of the worksheet are included:   * In the first version of the worksheet, some lines are graphed using a given equation, and some are graphed by reflecting a previous line. Students then must give the equation of the reflected line.   * In the second version, all lines are graphed using a given equation in slope-intercept form. Students also complete a chart identifying the slope and y-intercept of each line.   * In the third vers
