Answer 2

x = 10  & x + y =  7  is the line  joining the points (x,-3) and (2,5) whose inclination is  135 degree

Step-by-step explanation:

inclination of the line joining the points (x,-3) and (2,5) is 135 degree

slope of line = Tan(135°) = - 1

Slope of line =  (5 -(-3))/(2 - x)

=> 8/(2 - x) = - 1

=> 8 = x - 2

=> x = 10

(10 , - 3)  , (2 , 5)

y = -x + c

5 = - 2 + c

=> c = 7

y = -x + 7

=> x + y = 7
