Answer:
The point (-2,0) is on the line: False
The point (0,-2) is on the line: True
The graph represents the equation 2x-2y=4: True
The graph represents the equation 2x+2y=4: False
Explanation:
(-2,0) is not on the line, but (0,-2) is.
In order to find the answer to the last two, you must put the equation in y=mx+b form. The third question in y=mx+b form is y=x-2.
2x-2y=4
-2y=-2x+4
y=x-2, That is the equation.
The fourth question in y=mx+b form is y=-x+2.
2x+2y=4
2y=-2x+4
y=-x+2, That is not the equation.
