now, when the distance between the lines is zero, they meet and the rate of change that this happens is the difference between the slopes

\[y_1=m_1+b_1\]\[y_2=m_2+b_2\] the distance at x=0 is b1b2; the rate of change that effects this distance is m1m2; therefore:\[Y_d = (m_1m_2)X_d+(b_1b_2)\]

yw and so, the value of Xd where the distance "Yd" = 0 is then\[\frac{b_1b_2}{m_1m_2}\]
