Answer 1

Option (C)

Explanation:

Given formula of a line passing through
`(x_1, y_1)` and slope 'm' is,

`y-y_1=m(x-x_1)`

Further solving this equation,

`y-y_1=mx-mx_1` [By distributive property]

`y-y_1+mx_1=(mx-mx_1)+mx_1` [By adding
`mx_1` on both the sides]

`y-y_1+mx_1=mx`

`(y-y_1-mx_1)/(m)=(mx)/(m)` [Divide the equation by m]

`(y-y_1)/(m)-x_1=x`

Therefore, Option (C) will be the answer.
