# Find the equation of the line Passing through (2, 2 ) and inclined with the x-axis at an angle of 75°.

The line passes through (2, 2 )

θ = 750
m = tan 750 = tan(450 + 300) = = = Equation of the line in point-slope form is

y – y1 = m(x – x1)

y –2 = (x – 2)

( (y - 2 ) = ( +1)(x – 2)

( = x - 2 + x – 2)

or ( +y - 2 - 2 - 2 + 6) = 0

( - 1)x – ( - 1)y = 4 - 4

or ( + 1)x – ( - 1)y = 4( - 1)
