Answer:

Graph of the equation 2x +3y = 12 We have 2x +3y = 12 2x = 12 -3y x = (12-3y)/2 Putting y = 2 we get x = (12-3 x 2)/2 = 3 Putting y = -4 we get x = (12-3 x 4)/2 = 0 Thus, (3, 0) and (0, 4) are two points on the line 2x +3y = 12 The graph of line represents by the equation 2x + 3y = 12 (i) To find coordinates of the points when y = 3, we draw a line parallel to x axis and passing through (0,3) this lines meets the graph of 2x + 3y = 12 at a point p from which we draw a line parallel to y axis which process x axis at x =3/2 , so the coordinates of the required points are (3/2, 3). (ii) To find the coordinates of the points when x = -3 we draw a line parallel to y axis and passing through (-3, 0). This lines meets the graph of 2x +3y = 12 at a point p from which we draw a line parallel to x axis crosses y axis at y = 6, so, the coordinates of the required point are (-3, 6)
