Question

9. The inverse of an ordered pair on a graph is its reflection across the line y = x.

Answer 1

Answer:

9. Always true

10. Always true

11. Never true

12. Always true

13. Always true

14. Never true

Step-by-step explanation:

An inverse is defined as the reflection across the line y=x. Algebraically this means that x and y switch place in the inverse equation and in the coordinate points of a function.

A line will always give a line.

Example: y = 2x -2

Inverse: x = 2y -2 which when rearranged is y = 1/2 x +1.

This also means that the slope if greater than 1 for the function will have a slope less than 1 for its inverse.
