Question

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

Answer 1

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 :-)

Answer 2

1. y=48/x

2. y=0.4/x

3. the last graph

4. direct variation, y=7x

5. inverse variation, xy=8
