Among the following five propositions about conic sections:  
\\(①\\) In a plane, the trajectory equation of points whose distance ratio to a fixed point \\(A(1,0)\\) and a fixed line \\(l\\): \\(x=2\\) is \\( \dfrac {1}{2}\\) is \\( \dfrac {x^{2}}{4}+ \dfrac {y^{2}}{3}=1\\);  
\\(②\\) Point \\(P\\) is a moving point on the parabola \\(y^{2}=2x\\), the projection of point \\(P\\) on the \\(y\\)-axis is point \\(M\\), and the coordinates of point \\(A\\) are \\(A(3,6)\\), then the minimum value of \\(|PA|+|PM|\\) is \\(6\\);  
\\(③\\) In a plane, the trajectory of points whose distance ratio to two fixed points is a constant \\(λ(λ > 0)\\) is a circle;  
\\(④\\) If a moving point \\(M(x,y)\\) satisfies \\( \sqrt {(x-1)^{2}+(y+2)^{2}}=|2x-y-4|\\), then the trajectory of point \\(M\\) is a hyperbola;  
\\(⑤\\) If a line \\(l\\) passing through point \\(C(1,1)\\) intersects the ellipse \\( \dfrac {x^{2}}{4}+ \dfrac {y^{2}}{3}=1\\) at two distinct points \\(A\\) and \\(B\\), and \\(C\\) is the midpoint of \\(AB\\), then the equation of line \\(l\\) is \\(3x+4y-7=0\\).
