Find out whether the line representing the 5x-4y + 8 = 0 and7x + 6y -9 – InterviewSolution

1.	Find out whether the line representing the 5x-4y + 8 = 0 and7x + 6y -9 0 is co-incident. If so solve them graphically
Answer» 5x-4y+8=07x+6y-9=0a1/a2=5/7b1/b2=-4/6=-2/3since a1/a2 is not equal to b1/b2, then the solution is unique.that is the lines do not coincide, it intersect
