Heya User,

--> Slope of line given --> 2x - 3y + 18 = 0
=> 3y = 2x + 18
=> y = 2/3 ( x + 6 ) --> mx + c

--> Slope = m = 2/3
=> Slope of AP = -1 / ( 2/3 ) = -3 / 2 = -1.5
=> Equation of AP = 2y + 3x + 1 = 0

Given the two equations, we have the point AP as their common solution :-> P( -3 , 4 ) <--- Your Soln.
