Okay, here we have this:
Let's plug in each equation x = 2 to see which ones satisfy the value of "y" from the table.
A)
y=60(2)-80=120-80=40≠100 This option is incorrect
B)
y=80(2)-60=160-60=100 This option satisfies the value of the table.
C)
y=20(2)=40≠100 This option is incorrect
D)
y=2+80=82≠100 This option is incorrect
Finally we obtain that the correct answer is the second option.
