this question is really pissing me off

[late goblet]

It's 0.5

Look for 4 on the x-axis

On the 1st graph

And the x coordinate for the point on the graph has a y coordinate and it is 0.5 so 0.5 is ur answer

[full cedar]

Are you sure it’s wrong? Even I got 0.5

[full cedar]

This is a guess but could it be 0.25 cuz if y=1/x then y=1/4?

[hollow cargo]

that makes no sene, y=k/x

show the other 2 graphs

anyway its 0.25 (not because of above but)

x = 2, y = 1/2
so when x=4 y halves so y = 1/4

declan u got part A wrong so u would get part B wrong thats whats confusing

[full cedar]

Wdym by halves cuz half of 4 is 2

[hollow cargo]

when x doubles y halves

inverse proportionality

4 is double of 2 so x has doubled so y must halve

[hollow cargo]

oh yea k is 1 im confused how declan got confused

[full cedar]

So the answer is 1/4?

[hollow cargo]

yes

[hollow cargo]

do u understand how he got y=1/x?

[full cedar]

no

[hollow cargo]

inverse proportionality:
y= k/x
y=1/2 , x = 2
1/2 = k/2

so k must be 1

yea but A isnt the right graph btw

look at x = 2 on graph A its not 1/2

scroll down its one of the others

correct
