Answer:

slope = -1

Step-by-step explanation:

slope formula: (y2-y1)/(x2-x1)

(1-2) divided by (9-8) = -1/1 = -1

slope = -1

you can switch it up by doing (9-8) divided by (1-2), but it won't make a difference I think.

Which ordered pair represents the y-intercept of the graph of the equation y = -3x - 9?

Answer:

The answer to your question is  letter C. 7y³  + 7n²y²  - 22y²

Step-by-step explanation:

                                   y²(4y + 7n² + 2) - 3y² (-y + 8)

Multiply

                                 4y³ + 7n²y² + 2y² + 3y³ - 24y²

Use the associative property for like terms

                               (4y³ + 3y³) + (2y² - 24y²) + 7n²y²

Simplify like terms

                                7y³ - 22y² + 7n²y²   or    7y³  + 7n²y²  - 22y²
