If the axis is parallel to x axis, Latus Rectum = 1 and passing through (3,1) and (-5,5)
Help please. No idea. The axis parallel to x axis made it confusing.
Hello reiwardThe 'standard' parabola with axis parallel to the -axis has equationand if we move the vertex from the origin to the point , this equation becomes:
Now the latus rectum has length . So here , and the equation now becomes:Plug in the values of and at the two points you're given:
So the equation is:
which can be re-written as:
if you like.
