To investigate which of the choices satisfy the equation, substitute the values of the abscissas into the equation and solve for y. See if the value of y calculated is equal to the value of the ordinate of the point.

A. (7, -2) ; (2)(7) + 5y = 4 ; y = -2 EQUAL

B. (0, -1) ; (2)(0) + 5y = 4 ; y = 0.8 NOT EQUAL

C. (0, 1) ; (2)(0) + 5y = 4 ; y = 0.8 NOT EQUAL

D. (3, -2) ; (2)(3) + 5y = 4 ; y = -0.4 NOT EQUAL

Thus, the answer is letter A.
