Answer: (2, -10)
Down and left are negative right and up are positive.
Answer:
y = 46
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 23 when x = 8 , then
23 =
( multiply both sides by 8 )
184 = k
y =
← equation of variation
When x = 4 , then
y =
= 46
