Guided Notes
3 key concepts
- 1
When solving a system of equations by graphing, the solution is the x and y values that satisfy both equations, which is found at the point of intersection.
- 2
If two lines are graphed on the same coordinate plane and do not intersect, there is no solution and the system is called inconsistent.
- 3
When graphing lines in slope-intercept form (y = mx + b), 'm' represents the slope and 'b' represents the y-intercept.
