A system of equations has no solution. If y = 8x + 7 is one of the equations, which could be the other equation?
A system of linear equations can have no solution if the lines are parallel to each other. Looking at the given equation, it has a slope of 8. Any different equation having the same slope will belong to the system of equation without solution. So, the family of equations is: y = 8x + k where k is any real number but not equal to 7
