the equation of a straight line passing through p(3,4) and makes an inclination of 135 with x axis in clockwise direction. then the equation of line is

Answer 1

The slope of a line equals tan A, where A is the angle that the line makes with the x-axis
So the slope of your line is tan (-135°) = 1

then y = x + b
but (3,4) lies on it, ...
4 = 3 + b
b = 1

y = x + 1
or
x - y = -1
