There are certain cases that need to be taken into consideration: 1. If the lines intersect at one point the solution that fits all equations is exactly that point. 2. If the lines do not intersect at only one point the system has no solution because the lines 3. If the system of equations intersects completely overlaps the other line we say that we have an infinite number of solutions that fits the equations.
Step-by-step explanation: From one point, go over to the top/bottom of the other point then go down/up to the point (go from one point to the other) then the rise you did (1) over the run across (3) then the formula is rise over run. then divide.
