Answer is A. Y= -2x I would just plug in the numbers for y and x -12 = -2 (6) True -14 = -2 (7) True -16 = -2 (8) True -18 = -2 (9) True -20 = -2(10) True The rule Y= -12x can't be true since it would make all the Y values incredibly high. Also Y= -2x + 1 can't be true since that would mean -12 = -11 which is an incorrect statement.
The answer is A. Find the slope using the slope formula and you get -2/1. If you plug in a point from the table, for x and y value into the equation, you'll see that it is a true statement.
