Her pay increases $10.00 fore every hour she works

The slope of the line is 10 because you have to pick two points off of the graph, it doesn't matter what two points, and stick them in the formula: y²-y÷x²-x. Once you work out this formula, you get 10/1 which equals to the slope being 10.

MARKING AS BRAINLIEST!! Starr if given functions are inverse)!

Kitty [74]

Answer: They are inverses of each other

==========================================================

Explanation:

We'll need to compute h(f(x)) and f(h(x)) to see if we get x each time.

$h(x) = 9x-4\\\\h(f(x)) = 9(f(x))-4\\\\h(f(x)) = 9\left(\frac{x+4}{9}\right)-4\\\\h(f(x)) = x+4-4\\\\h(f(x)) = x\\\\$

and,

$f(x) = \frac{x+4}{9}\\\\f(h(x)) = \frac{h(x)+4}{9}\\\\f(h(x)) = \frac{9x-4+4}{9}\\\\f(h(x)) = \frac{9x}{9}\\\\f(h(x)) = x\\\\$

Both composite functions lead to x each time.

The equations h(f(x)) = x and f(h(x)) = x being true means each function is the inverse of the other.
