If `y=f(x)` makes positive intercepts of 2 and 1 unit on x and y-coordinates axes and encloses an area of `3/4` sq unit with the axes, then `int_0^2 x f'(x)\ dx`, is

If y=f(x) makes positive intercepts of 2 and 1 unit on x and y -coordinates axes and encloses an area of (3)/(4) sq unit with the axes, then int_(0)^(2)xf'(x)backslash dx, is

If y= f(x) makes positive intercepts of 2 and 1 unit on x and y coordinate axes and encloses an area of 3/4 square unit with the axes then int_0^(2) d^(')(x) dx is

If a line perpendicular to 2 x-3 y+7=0 forms a triangle with the coordinate axes whose area is 3 sq. units, then the equation of the line(s) is

If a straight line is passing through the point of intersection of the lines 3x - 4y + 1 = 0, 5x + y - 1 = 0 and making equal non-zero intercepts on the coordinate axes, then the area (in sq. units) of the triangle formed by this line with the coordinate axes, is

The equation to the line parallel to 2x+3y-5=0 and forming an area 4//3 sq. unit with the coordinate axes is
