ax + by - {a^2} = 0,\;

where

a,b

are non-zero, is the equation to the straight line perpendicular to a line

l

and passing through the point where

l

crosses the x-axis. Then, equation to the line

l

View answer and explanation

Correct option: B

\frac{x}{a} - \frac{y}{b} = 1

Option B (

\frac{x}{a} - \frac{y}{b} = 1

) is correct because it represents the equation of the line

l

that is perpendicular to the given line and passes through the x-intercept of the given line.
