Urgent! please help! (row 1-2) Select if each situation represents a nonlinear function, a linear function, or not a function.

Table 1 is definetely non-linear thats because if 10 - 8

then you multiply both sides by 4 you get 40 - 32 but instead of 32 it says 23.

Table 2 is also non-linear because if 8 - 4 that means y=x/2 but for 20-16 it should be 20-10 if it was linear but its not

BOTH ARE NON-LINEAR

it would rotate about 180 degrees.
