If a line passes through the point (1, 2) and cuts off positive intercepts on the x–axis and y–axis in the ratio 2 : 3, find the equation of the line.
7 = 3x + 2y
3 = 2x + 7y
5= 3x + 8y
4 = 3x + 2y
Find the equation of a line that cuts off equal intercepts on the cordinate axis and passes through the point (2, 3).
Find the equation of a circle which passes through the origin and cuts off intercepts -2 and 3 from the x-axis and the y-axis respectively.
