the graphed line shown below is y = -4x - 12

[tex]\boxed{y=-4x}[/tex]
A linear equation is an equation of a line while a system of linear equations contains two or more linear equations that work together. A system of two linear equation has no any solution when the lines have the same slope. The graphed line shown in the Figure has an equation [tex]y=-4x-12[/tex] being the slope [tex]m=-4[/tex]. Thus, from the options the line that has the same slope is [tex]y=-4x[/tex]. Finally, these two lines have no any because they are parallel.
