It is -3 degrees Celsius per 1 hour. <span />
Answer:
Step-by-step explanation:
y = kx ;
k = 
; x = 
~~~~~~~~~~~~~
<em>k </em>= 
÷ 1 =
= × ( - 8 ) = - 4
= × ( - 4 ) = - 2
= × 2 = 1
= 
÷ = 
= - 
÷ = -
= 0
( x , y ) : ( - 8 , - 4 ), ( - 4 , - 2 ), ( 2 , 1 ), ( 1 , ), ( , ), ( - , - ), ( 0 , 0 )
The coordinate of c is 2
On a number line 'a' is at 11
and , 'b' is at -4
To find the coordinate of c
Now, According to the the question:
'a' and 'b' are -4 -11 = -15 units apart.
'ac' = 3/5 .'ab'
'ac'= 3/5 . (-15)
'ac' = -9
Now, Coordinate of 'c'
= 11 -9
= 2
Hence, The coordinate of c is 2
