Hi
Parabola opening to the rght
 The standard form is {{{( y-hyk)^2 = 4p(x -k)}}}, where  the focus is (h,k + p) 
vertex at the origin. directrix: x = -2  thus p=2
 y^2 = 8x


{{{drawing(300,300,   -6, 6, -6, 6,  blue(line(-2,6,-2,-6))  , grid(1),
circle(0, 0,0.3),
circle(2, 0,0.3),
graph( 300, 300, -6, 6, -6, 6,0, 2.828sqrt(x), -2.828sqrt(x) ))}}}
