Question

Is the system consistent or inconsistent? y= -1/2x-1 and y=3x+3

Answer 1

i am working on it

Answer 2

r u still there?

Answer 3

Yes, haha.

Answer 4

i am working on it

Answer 5

The system of equations
a1x + b1y + c1 = 0
a2x + b2y + c2 = 0

(i) is consistent with unique solution, if a1/a2 is not equal to b1/b2
i.e the lines represented by equations are not parallel.

(ii) consistent with infinitely many solutions, if a1/a2 = b1/b2 = c1/c2
i.e. the lines represented by equations are coincident.

(iii) inconsistent, if a1/a2 = b1/b2 is not equal to c1/c2
i.e. the lines represented by equations are parallel and non-coincident.

Now use this result and find the answer yourself :)
