Equation of the line passing through `(1,2)` and parallel to the line `y=3x-1` is

Options

A. `y+2=x+1`
B. `y+2=3(x+1)`
C. `y-2=3(x-1)`
D. `y-2=x-1`

Answer

C

Explanation

Since, the line passes through `(1,2)` and parallel to the line `y=3x-1`.
So, slope of the required line `m=3` [`because` of `y=3x-1` is3]
Hence, the equation of line is `y-2=3(x-1)`
