Question

Help!!!!!!!!!!!!!!!!!!

Answer 1

1. y=48/x

2. y=0.4/x

3. the last graph

4. direct variation, y=7x

5. inverse variation, xy=8

Answer 2

1)   y = k . 1/ x
 >> 6 = k . 1/8
>> k = 48
so, equ.  is y = 48 / x
option d)

2)  y = k. 1/x
>> 0.2 = k. 1/2
>> k =0.4
>> y= 0.4 / x
option b )

3)  graph of   y = 3/x 
for  x= 0, y=  infinity 
x= 1, y=3  and x=3, y=1  and so on..
option d)

4)  option c)   , y= 7x
by putting values

5)  option d)   , y = 8/ x
by putting values
hope it helped :-)
