Question

(HELP PLEASE)

Answer 1

ANSWER

See below

EXPLANATION

Given the system of linear equation:

$y = m_1x + b_1$

$y = m_2x + b_2$

If

$m_1 \ne \: m_2$

then the two equations, will intersect at one. The system has unique solution.

If

$m_1 =m_2 \: and \: b_1 \ne \: b_2$

then, the two equations are parallel and the system will not have a solution.

If

$m_1 =m_2 \: and \: b_1 = \: b_2$

Then, the two equations will coincide.

There is infinitely many solutions.
