Identify the slopes of both equations. The slope is the coefficient of \(x\) in each equation. Here, both slopes are \(\frac{1}{4}\).
Compare the slopes. Since both slopes are equal, the lines are either parallel or the same line.
Check the y-intercepts (the constant terms). The first equation has a y-intercept of \(11\), and the second has a y-intercept of \(-6\).
Since the slopes are equal but the y-intercepts are different, the lines are parallel and will never intersect.
Conclude that the system has no solutions because parallel lines do not intersect.
