# Find the equation of the straight lines passing through the following pair of points:

(a cos α, a sin α) and (a cos β, a sin β)

Answer :

Given: ( x_{1},y_{1}) = (a cos α, a sin α), ( x_{2},y_{2}) = (a cos β, a sin β)

Concept Used:

The equation of the line passing through the two points ( x_{1}, y_{1}) and ( x_{2}, y_{2}).
