Key concepts

3 concepts

  1. 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. 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. 3

    When graphing lines in slope-intercept form (y = mx + b), 'm' represents the slope and 'b' represents the y-intercept.

Quick comprehension check

Solve the following system of equations by graphing. Clearly plot each line on the coordinate plane and indicate the point of intersection. Number the coordinate plane axes from -5 to 5. y = x + 3, y = -x + 1
