I know this isn't the place you guys jump to for homework help, but i am. I got some gay take-home test for algebra, and i'm stuck as fuck on a problem. I called my buds and they're clueless. PLEASE HELP!!!

Ok, here's the problem. Given the information you have to write the equation of the conic section. As in, determine if it's a parabola, ellipse, or hyperbola, then proceeding to write the equation.

1) The set of points equidistant from (2,4) and y=1

Not sure if I understand the question right but if you draw a line between those two points and look at the middle of this line you have one point which has the same distance to both coordinates. If you want to look for other points with the same distance you can start from this point and see that they all have to form a triangle with the same length of sides based on the line you already drew. If you connect the points you figure out like this it looks like a linear function. You just have to insert some coordinates to get the paramters then.

Well it's a parabola because the equation forms a straight line. And the equation is something like y=1/2x + 1.

I did that by finding the gradient which is just 2 divided by 4 and then the y intercept is 1! Tada.
