-20/10=-2 degrees every 1000 feet.
9) Suppose that the function f(x) is the parrent function and the graph of the function g(x)=f(x)-a can be obtained from the graph of the parrent function f(x) by shifting down a units.
Rewrite the expression for the function in the following way:
g(x)=32x-9=32x+8-8-9=32x+8-17=f(x)-17.
This shows that the shift down is made by 17 units.

y = -3x

Step-by-step explanation:

Given

The attached graph

Required

Determine the graph equation

To do this, we pick any 3 corresponding points of x and y

(x_1,y_1) = (0,0)

(x_2,y_2) = (2,-6)

(x_3,y_3) = (-4,12)

The equation can then be solved using linear interpolation as follows:

$\frac{y-y_3}{x-x_3} = \frac{y_2 - y_1}{x_2-x_1}$

This gives:

$\frac{y-12}{x-(-4)} = \frac{-6 -0}{2-0}$

$\frac{y-12}{x+4} = \frac{-6 -0}{2-0}$

$\frac{y-12}{x+4} = \frac{-6}{2}$

$\frac{y-12}{x+4} = -3$

Multiply both sides by x + 4

$(x + 4) * \frac{y-12}{x+4} = -3 * (x + 4)$

y - 12 = -3 *(x + 4)

Open bracket

y - 12 = -3x -12

Add 12 to both sides

y - 12+12 = -3x -12+12

y = -3x
