y = -2x + 4
The graph of the equation is the set of points that are solutions to the equation. 
The equation 2x + y = 4 is represented by the same graph. 
For point (1, 2): 2 = -2(1) + 4 = -2 + 4 = 2. 
Therefore, the point (1, 2) lies on the the graph of the equation. 
For the point (0, 2): 2 ≠ -2(0) + 4 = 0 + 4 = 4. 
Therefore, the point (0, 2) DOES NOT lie on the graph of the equation.
