7.1 Solving Systems by Graphing I can solve systems of equations by graphing. Don’t forget to write this “I Can” in your target sheet.
7.1 Solving Systems by Graphing System of Linear Equations – Two or more linear equations together. No Solution – When the graphs of equations are parallel lines. Infinitely many Solutions – When the graphs of equations are the same line.
Steps for Solving System of Equations by Graphing 1. Graph each equation on the same coordinate plane. * Use form. * Plot the y-intercept (b). * Use slope to get other points. 2. Find the point of intersection (Place where two lines cross). 3. Check by plugging point back into both equations (like bell ringer).
