9. the inverse of an ordered pair on a graph is its reflection across the line y = x. always true sometimes true never true 10. the inverse of a linear function is a linear function. always true sometimes true never true 11. the inverse of a line with positive slope is a line with negative slope. always true sometimes true never true 12. the inverse of a line with a slope greater than 1 is a line with slope less than 1. always true sometimes true never true 13. the inverse of the inverse of point (x, y) is the original point. always true sometimes true never true 14. the line y = k, where k is a constant, has an inverse. always true sometimes true never true

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.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3
