Question
If in two linear equations ax + by = c and dx + ey = f
and a/d = b/e = c/f then, which of the following is true about the two equations?Solution
Given, ax + by = c dx + ey = f Formula: If the given equations of straight line are a1x + b1y + c1 = 0 and a2x + b2y + c2 = 0, then If a2b1 – a1b2 = 0 or a1/a2 = b1/b2 , then lines are parallel If, a1/a2 = b1/b2 = c1/c2 , then lines are coincident. Calculation: ax + by = c dx + ey = f a/d = b/c = e/f If both lines same now we can say both lines are coincident.
