Show that the two ordered pairs are solutions to the given equation. Then use the graph of the two points to determine another solution. Answers may vary.x + 2y = 8; (2, 3), (-2, 5)
What will be an ideal response?
Show that (2, 3) is a solution:
| x + 2y | = 8 |
| 2 + 2(3) | =? 8 |
| 2 + 6 | =? 8 |
| 8 | =? 8 | TRUE |
x + 2y = 8
| -2 + 2(5) | =? 8 |
| -2 + 10 | =? 8 |
| 8 | =? 8 | TRUE |
