Question

16.Straight line passing through the points (-1, -1), (0, 0) and (1, -1) has equation ​

Answer 1

Answer:

For point (0,0), LHS =0+0=0= RHS

For point (−1,1), LHS =−1+1=0= RHS

For point (1,−1), LHS =−1−1=0= RHS

Hence, the line x+y=0 passes through all the points (0,0),(−1,1) and (1,−1)
