Answer 1

Answer:

Unique solution

Step-by-step explanation:

 a1 is the coefficient of a of first equation, b1 is the coefficient of b in the first equation and c1 is the constant. Similarly, a2 is the coefficient of a in the second equation, b2 is the coefficient of b in the second equation and c2 is the constant in the second equation.

• If a1/a2 ≠ b1/b2 than there is a unique solution and the lines are consistent. These lines intersect at one point.
• If a1/a2 = b1/b2 ≠ c1/c2 then there is no solution. These lines are parallel.
• If a1/a2 = b1/b2 = c1/c2 then there is a solution and the lines are co linear.
