Answer:
D
Explanation:
First, put the equation 2x + y = 4 into mx + b = y form.
2x + y = 4
-2x -2x
y = -2x + 4
Since your m is -2, the slope is suppose to be negative. So you can cancel out choices A and B. (They show a positive slope.)
Since your y is positive 4, look on the graph the has a line going through positive 4 on the y-axis.
D is your answer.
