    A line passes through (2, 2) and is perpendicular to the line \[3x+y=3.\] What is its y-intercept?

    A)  \[\frac{1}{3}\]

    B)  \[\frac{2}{3}\]

    C)  \[1\]

    D)  \[\frac{4}{3}\]

    Correct Answer: D

    Solution :

    Equation of the line perpendicular to \[3x+y-3=0\]is \[x-3y+c=0\] Since, it passes through (2, 2). \[\therefore \] \[c=4\] \[\therefore \]Equation of line perpendicular to \[3x+y-3=0\]is\[x-3y+4=0\] For y-intercept, put \[x=0\] \[\therefore \] \[y=\frac{4}{3}\]
