Directions: Tell whether the following equations are linear or not. Write L if the equation is linear, otherwise NL. Write your answer on the space provided before each number.
1. x + 2y = 8
2. x² - 2x + 10 = 0
3. x² + 5× = 0
4. x² - 2 = 0
5. 4x + 10y - 3 = 0
6. 3x² + 5× = 3x² - 2x + 9
7. x (x + 4) = x² - 5x
8. x² + 3x - 4 = 2x² - 8
9. (2x - 4) (x + 5) = 0
10. (2x - 4)(x + 5) = (x + 3)(x - 2)​
