Question

If a pair of linear equations has infinitely many solutions, then its graph is represented by a pair

of ............... lines.​

Answer 1

If a pair has infinitely many solutions, then it's graph is represented by a pair of infinitely lines

Answer 2

Answer:

If a pair of linear equations has infinitely many solutions, then its graph is represented by a pair of coincident lines.

Step by step explanation:

The linear equation is represented in the form

$ax + by = r$

.Every solution of the equation which satisfies the equation must lie on the line representing the equation. The pair of linear equations have infinitely many solutions if

$\frac{a_1}{a_2} = \frac{b_1}{b_2} = \frac{c_1}{c_2}$

For example, consider the equation

$-6x+ 4y=2$

$3x - 2y =-1$

The graph of = the solution of the equations is a coincident line.

Therefore,

If a pair of linear equations has infinitely many solutions, then its graph is represented by a pair of coincident lines.
