i this question the rule of

Y=Y applies

F(x)=2x
y=-x

so, 2x=-x

so the answer is the intersection of the 2 lines.....

i guess X will finally be -0.5 (just imagined the line), draw y=-x and check the intersection

a line needs 2 points.......but take 3 to be sure of it

take,

Y=0  >> (0)=-X >> X=0
Y=1 >> (1)=-X >> X= -1
Y=-1 >> (-1)=-X >> X=1

(0,0) (1,-1) (-1,1)

now plot the line and find the intersection

i didnt use Y=2 because on the grid the last point is x=-1.......use points that are available :D

Q11.(ii)
Why is it 0.255 shouldn't it be 0.254?
Q7. Isn't it 1:8? The mark scheme says 8:1!

11ii)Because it could be0.25499999999999999999999999999999999999 etc so to save ink and planet they say 0.255
7Juans model is twice as big. It is 50 times smaller but Pedros is 100 times smaller. Twice as big means 8 times the volume.
