Question
Find the equation of a line passing through (3,7) and making an angle of 60° with the negative direction of the x-axis.
Solution
m = tan (180° - 60°)
= -tan 60°
= -`sqrt3`
Equation of line is given by
`("y" - "y"_1)/("x" - "x"_1)` = m
= `("y" - 7)/("x" - 3) = sqrt3`
`sqrt3"x" + "y"- 7 - 3sqrt3 = 0`
