The general equation of a conic in the form of $Ax^2+Bxy+Cy^2+Dx+Ey+F=0$ if $B=0$ (i) defines a parabola if $AC=0$ (ii) defines an ellipse if $AC\gt0$ and $A\ne C$ (iii) defines an a circle if $AC\gt0$ and $A=C$ (iv) defines a hyperbola if $AC\lt0$ Here $A=0,C=1$, hence $AC=0$, thus it is a parabola.
