Flashcards : Foundations of Coordinate Geometry — 16 cartes

$(x-h)^2 + (y-k)^2 = r^2$.

Inverse proportion function, $ y=rac{k}{x} $.

Checks if a graph is a function.

Center $(h,k)$ and radius $r$.

Square root of sum of squared coordinate differences.

Product of variables is constant ($ xy=k $).

Average of x's and y's coordinates.

Use point-slope or two-point formula.

$ y = mx + c $, a straight line.

Negative reciprocal slopes.

Indicates line steepness and direction.

Equal slopes, different intercepts.

Hyperbola with asymptotes at axes.

Function assigns exactly one y to each x.

Set of ordered pairs, may or may not be a function.

Solve equations simultaneously or graphically.
