Q3 of 39 Page 114

Determine the equation of the line in each of the following graphs:

The general equation of the line is y = mx + c, where m and c are constants.


From the graph, it is visible that the line passes through the point (2, 0) and (0,-3).


Substituting both the values in general equation, y = mx + c, we get


0 = m(2) + c ..(i)


-3 = m(0) + c ..(ii)


From equation (ii), we get c = -3,


Putting c = -3 in equation (i),


2m + (-3) = 0



Putting both m and c in general equation y=mx+c,






So equation of line is 3x-2y = 6
