If y=x2, then (0,0) is the centre.
If 4a(y-k)=(x-h)2, then (h,k) is the centre, where a is the focal length.

How do you make a linear equation go through three points?
In general, a linear equation CANNOT be made to go through three points. That will only happen if the three points are collinear and in that case, the equation of the line will only require two points.
How do you find the equation for a parabola?
u look at it.... :-) hey I'm learning about parabolas too

What careers use parabolas?
One career that might use a parabola is a mathematics teacher. Geometry teachers might also use parabolas. A parabola is a line consisting of points that are connected and spaced unilaterally.
How can you tell if an equation is a parabola?
Any and all conics, parabolas included, take the form Ax2 + Bxy + Cy2 + Dx + Ey + F = 0, with A, B, and C not all zero. The parabolas themselves have B2 - 4AC = 0.
A parabola has a vertex at -3 -2 what is its equation?
-1
What does a system of equation with no solution look like?
Functions (lines, parabolas, etc.) whose graphs never intersect each other.

What is the equation of the points (31) and has a radius length of 2?
If you mean a circle center at (3, 1) and a radius of 2 then the equation of the circle is (x-3)^2 +(y-1)^2 = 4
What is the equation of the points (-12) and has a radius of length 3?
If you mean a circle center at (3, 1) and a radius of 2 then the equation of the circle is (x-3)^2 +(y-1)^2 = 4
