A candle company determines that, for a certain specialty candle, the supply function is $$p = m_1x +b_1$$ and the demand function is $$p = m_2x +b_2$$, where p is the price of each candle, x is the number of candles supplied or demanded, and $$m_1$$, $$m_2$$, $$b_1$$, and $$b_2$$ are constants. At what value of x do the graphs of the supply function and demand function intersect?
(1) $$m_1 = -m_2 = 0.005$$
(2) $$b_2 - b_1 = 6$$
