Guided Notes

3 key concepts

  • 1

    When solving a system of linear equations by graphing, the solution is the intersection of the two graphs, representing the x and y values that satisfy both equations.

  • 2

    To graph the linear equation 5x + 3y = 7, we can find two points such as the intercepts: when x=0, y=7/3, and when y=0, x=7/5.

  • 3

    To check if the point (2, -1) is a solution to the system, substitute x=2 and y=-1 into both equations: 5(2) + 3(-1) = 7 and 3(2) - 2(-1) = 8.
