<h2>Answer:</h2><h2 />
There are two ways to solve a system of linear equations (equations representing a line) of two or more equations and find if there is a solution (or solutions) that satisfies all the equations in the system at the same time or <u>if there is not solution</u>.
1. Graphically, plotting the graphs of the lines and determining if they intersect and in which point.
2. Algebraically, combining the equations to delete each unknown except one, and then clear it.
In this context, a system of linear equations <u>has no solution</u> when the two lines are <u>parallel</u> and distinct, that is, they do not intersect or there is no intersection point.
Now, when two lines are parallel they have the same slope. We will be able to recognize it if we write the equation in the slope-intersect form:

Where
is the slope and
the intersection point.
