For the lines (y=2) and (y=9), how many solutions will there be?

Answer and explanation

Correct answer: No solution

A pair of linear equations has a solution at every common point of their graphs. The equation y=2 is a horizontal line containing points whose y-coordinate is 2, while y=9 is another horizontal line at height 9. Because 2 and 9 are different, no point can lie on both lines: a common point would need to have y=2 and y=9 simultaneously. The lines are distinct and parallel, so the system has zero solutions. Hence option B is correct. Infinitely many solutions would occur if both equations represented the same line, one solution would require intersecting lines, and two solutions cannot occur for two distinct linear lines.
