Systems by graphing — Homework
For each system, list 4 points for each line, find where they cross, and check the crossing point in both equations.
- 1.System: y = x + 3 and y = -x + 7. List points and find the crossing point.
- 2.Check (2,5) in both equations from above.
- 3.System: y = 2x - 1 and y = x + 2. List points and find the crossing point.
- 4.Check (3,5) in y = 2x - 1.
- 5.Explain in your own words why the crossing point of two graphed lines is called "the solution" to the system.
