Grade 8 | Unit 4 | Lesson 13: Solving Systems of Equations | Practice Problems

Write equations for the lines shown. Description: Graph of two intersecting lines in the xy-plane. Scale negative 8 through 8 on both axes. The first line slants upward and right, crosses the y axis at 2, and passes through the point 1 comma 5. The second line slants downward and to the right, crosses the y axis at 8, and passes through the point 1 comma 5. Describe how to find the solution to the corresponding system by looking at the graph.
