Step-by-step explanation:

BC is the bisector of $\angle ABQ$

$\therefore \angle ABC \cong \angle CBQ..(1)\\\angle CBQ \cong \angle CAB..(2) \\(\angle 's\: in \: alternate\: segments) \\$

From equations (1) & (2)

$\angle ABC \cong \angle CAB\\\therefore AC = BC$

(Because sides opposite to equal angles are equal)

Hence Proved

Answer:

As the slope is -2, so the rate of change of the function is:

rate of change of function = -2

Step-by-step explanation:

The slope is basically the rate of change of a function.

Let us take the two points from the graph

(0, 5)

(4, -3)

Taking the slope between two points to determine the rate of change of a function

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(0,\:5\right),\:\left(x_2,\:y_2\right)=\left(4,\:-3\right)$

$m=-2$

As the slope is -2, so the rate of change of the function is:

rate of change of function = -2
