  1. MPM2D – Linear Systems – Analyzing Linear Systems Single Equations and Systems of Equations We can find a single solution for an equation with 1 variable: We cannot find a single solution if we have an equation with 2 variables: This is a linear equation with an infinite number of solutions, such as (0, 4) , (1, 6) , and (-2, 0)

  2. However, 2 linear relations could intersect at a single point, which might provide the solution that is needed. MPM2D – Linear Systems – Analyzing Linear Systems Single Equations and Systems of Equations (5, -2)
