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 being the slope . Thus, from the options the line that has the same slope is . Finally, these two lines have no any because they are parallel.
