      Let us see the solution to your problem.


      Slope of the line(m) = [ 5 - 2] / [ 1 - (-1)] = 3 / 2


      Using the point slope formula, we have


      i.e. y - y1 = m ( x - x1) [ Hint: You can take any point given in the problem]


      i.e. y - 2 = 3/2 [x - (-1)]


      i.e. y - 2 = 3/2 ( x +1 )


      i.e. 2y - 4 = 3x +3


      i.e. 3x -2y + 7 = 0 is the required equation of the line.


      Hope this has helped you to some extent. Now solve the other related problems with your friends.
