Which of the following lines is not parallel to the line 3y + 2x + 7 = 0?
3y + 2x - 7 = 0
9y + 6x + 17 = 0
24y + 16x + 19 = 0
3y - 2x + 7 = 0
15y + 10x - 13 = 0
Correct answer is D
Two lines are said to be parallel if the slope of the two lines are equal.
The equation : 3y+2x+7=0
3y=−2x−7
y=−23x−73
dydx=−23
All the options have the same slope except 3y−2x+7=0.
