A line passes through the point `(2,2)` and is perpendicular to the line `3x + y =3,` then its `y`-intercept is

Text Solution

Verified by Experts

Slope of line `3x + y = 3 is m1 = -3`
Slope of perpendicular line, `m2 = 1/3 (since m_1m_2 = -1)`
Equation of line passing through`(2, 2) `with slope `1/3` is
`(y – y_1) = m(x – x_1)`
