Step-by-step explanation:

Step 1: Define

3m³ - 4m² + 8 - (-4m³ + 7m² - 5m - 9)

Step 2: Simplify

[Distributive Property] Distribute negative:                                                  3m³ - 4m² + 8 + 4m³ - 7m² + 5m + 9Combine like terms (m³):                                                                                7m³ - 4m² + 8 - 7m² + 5m + 9Combine like terms (m²):                                                                                7m³ - 11m² + 8 + 5m + 9Combine like terms (Z):                                                                                   7m³ - 11m² + 5m + 17

The answer will be y=-5+0 because the slope is -5 and the it has to go through y-axis 0
