Answer: I) Parallel Lines II) Coincident Lines
Step-by-step explanation:
In the first part, a1/a2 = b1/b2 ≠ c1/c2
Thus, it forms a pair of parallel lines
In the second part, a1/a2 = b1/b2 = c1/c2
Thus, it forms a pair of coincident lines
NOTE: Here 'a' means the coefficient of x, 'b' means the coefficient of y and 'c' means the constant number meaning the number without variable.
