Question 1022419
<font face="Times New Roman" size="+2">


Since one row of the matrix is a scalar multiple of the other, the determinant will equal zero.  However, the *[tex \Large D_y] and *[tex \Large D_x] matrices do not have scalar multiple rows and therefore, have non-zero values.  Conclusion: the system is inconsistent, i.e. the solution set is empty, and the graphs are parallel lines.

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
