If the intersection of the line y = 2X-4 and the line y = 4x + B is in the third quadrant, the value range of B is obtained,

If the intersection of the line y = 2X-4 and the line y = 4x + B is in the third quadrant, the value range of B is obtained,

By solving the equations of y = 2X-4 & nbsp; and y = 4x + B & nbsp;, the coordinates of intersection point are obtained
