उत्तर

4/3

The equation of the line perpendicular to 3x + y = 3 is given below:

x \[-\] 3y + \[\lambda\] = 0

This line passes through (2, 2)

2 \[-\] 6 + \[\lambda\] = 0

\[\Rightarrow \lambda = 4\]

So, the equation of the line will be

x\[-\] 3y + 4 = 0 

\[\Rightarrow y = \frac{1}{3}x + \frac{4}{3}\]

Hence, the y-intercept is \[\frac{4}{3}\].
