The solution is always shown as a graph. Example 6.8.2: How to Solve a System of Linear Inequalities by Graphing. Solve the system by graphing: {y ≥ 2x − 1 y < x + 1. Solution:The second inequality is y is less than 2x minus 5. So if we were to graph 2x minus 5, and something already might jump out at you that these two are parallel to each other. They have the same slope. So 2x minus 5, the y-intercept is negative 5. x is 0, y is negative 1, negative 2, negative 3, negative 4, negative 5.1 exam per unit, course diagnostic, and course final exam.
