Guided Notes
3 key concepts
- 1
When graphing a system of equations, the intersection of the lines represents the x and y pair that satisfies both equations.
- 2
A system of equations is when you have 2 equations that contain your x and y values, and the solution is where the lines intersect.
- 3
To solve a system of equations graphically, graph both equations and find the point of intersection, which represents the solution to both equations.
