Answer:
![100(0.5)^{x}](https://tex.z-dn.net/?f=100%280.5%29%5E%7Bx%7D)
Step-by-step explanation:
According to the graph, the y int is at 100
so that is the starting point
Then at 1 it is at 50
is 2 so that means it is reduced by half
Just to make sure,
is also /2 so that means it is the slope
Since it is a decay, the slope has to be less than one so you get the reciprecol of 2 to get....
![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
Answer:
1
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
3-2/9-8
1/1

Best of Luck!
Answer:
Step-by-step explanation:
39). y =
x + 3
40). m =
y -
= m( x -
)
(- 7, 5)
( - 12, 4)
m = ( 4 - 5 ) / ( - 12 + 7) = 1/5
y - 5 = (1/5)(x + 7) ⇒ y =
x + 6.4
