Answer:
Explanation:
1). y + 2x < 6 
 (y + 2x) - 2x < 6 - 2x
  y < -2x + 6 [Slope intercept form of the inequality]
2). y + 2x < 6
 Since there is no sign of equal to (=) in the given inequality therefore, line graphed will be dashed.
Notation of less than (<) denotes the area down the line. 
Option (4) will be the answer.
3). y + 2x < 6
 x ≤ 2
