Show that for any value of m the equation mx-y =4m-3 represents a straight line passing through a fixed point. What is the fixed point?

Text Solution

Verified by Experts

`m_1x-y=4m_1-3-(1)`
`m_2x-y=4m_2-3-(2)`
`y=4m_1-3-m_1x`
`m_2x-(3-4m+m_1x)=4m_2-3`
`x(m_2-m_1)-3+4m_1=4m_2-3`
`x(m_2-m_1)=4(m_2-m_1)`
`x=4`
`y=3-4m_1+m_1x`
