Answer 1

Answer:

-2

Step-by-step explanation:

Rise over run

Pick a point and check how much it goes vertically, then divide it by how much it goes horizontally.

Answer 2

Answer:

Option A

Step-by-step explanation:

The given function is a linear function therefore rate of change of this function will be the slope of the given line.

Since this line passes through two points ( 0,1 ) and ( 0.5 0 )

the slope of the line = $\frac{(y-y')}{(x-x')}$

                     slope   = $\frac{(1-0)}{(0-0.5)}$

                                 = ( -2 )  

Therfore, Option A will be the answer.
