I got y=2/3x + 10 , i hope that’s right!
2. the scale factor is x= 4.5 cm
this is because when u see how much it dilated from 4cm to 2cm it divided from 2, so if u did the same for the other number. Which is 9, it’s 9/2 which equals 4.5
Direct variation is of the form y=kx (inverse variation is of the form y=k/x)
I am fairly certain it is C
