Question

Find whether (0,-3)is asolution of. Linear equation,x-y+3=0.

Answer 1

yes this point is the solution of this equation when we put x 0 then the value of y is -3 and we put y -3 then x 0

Answer 2

(0,-3) is the coordinate where x=0and y=-3.
So we have to substitute these values in equation.
x-y+3=0
(0)-(-3)+3=0
+3+3=0
9=0 which is incorrect therefore (0,-3)is not a solution for equation x-y+3=0.
