Line BC is represented by 3x + 2y = 8. Line AD is represented by –3x – 2y = 6. What is the relationship of line BC to line AD? E xplain how the sum of the equations demonstrates this relationship.
2 answers:
Sample Response: Line BC is parallel to line AD. The system of equations has the sum 0 = 14. Since this is a false equation, the system has no solution, which means the lines will never intersect.
The correct answer for this question is this one: The equations are: <span>BC: 3x + 2y = 8. The slope of line BC is -3/2 y = -3/2 + 4 AD: –3x – 2y = 6. The slope of line AD is -3/2 y = -3/2x - 3</span> So the relationship of the two lines is parallel lines. Hope this helps answer your question and have a nice day ahead.

A graph shows ...
... absolute minimum: 5, at x=-1 and x=1
... absolute maximum: 8, at x=2
It’s 12 I from what I think
