The level curves in this case are just going to be lines So, for instance, if we take the level curve at z equals 0, then we have just the equation 2x plus y equals 0 And so that has intercept so we're looking at so 0 equals 2x plus y, so that's just y equals minus 2x So that's this level curveIf you take a perfectly horizontal sheet or plane that's parallel to the xyplane, and you use that to slice through your threedimensional figure, then what you get at the intersection of the figure and the plane is a twodimensional curve What we want to be able to do is slice through the figure at all different heights in order to get what we call the "level curves" of a functionThe level curves of the function \(z = f\left( {x,y} \right)\) are two dimensional curves we get by setting \(z = k\), where \(k\) is any number So the equations of the level curves are \(f\left( {x,y} \right) = k\) Note that sometimes the equation will be in the form \(f\left( {x,y,z} \right) = 0\) and in these cases the equations of the level curves are \(f\left( {x,y,k} \right) = 0\)

Definition The level curves of a function f of two variables are the curves with equations f (x,y) = k, where k is a constant (in the range of f ) A level curve f (x,y) = k is the set of all points in the domain of f at which f takes on a given value k In other words, it shows where the graph of f has height kThe level curve equation x 2 − y 2 = 0 factors to (x − y) (x y) = 0 This equation is satisfied if either y = x or y = − x Both these are equations for lines, so the level curve for c = 0 is two lines If c ≠ 0, then we can rewrite the level curve equation c = x 2 − y 2 asThe level curves (or contour lines) of a surface are paths along which the values of z = f (x,y) are constant;

Then the curves obtained by the intersections of the planes $z = k$, $k \in \mathbb{R}$ with the graph of $f$ are called the Level Curves of $f$ From the definition of a level curve above, we see that a level curve is simply a curve of intersection between any plane parallel to the $xy$ axis and the surface generated by the function $z = f(x, y)$Well, if you think about it, if I fix the value of z, then this is exactly the equation for the circle with radius square root of z So level curves, level curves for the function z equals x squared plus y squared, these are just circles in the xyplaneAccording to the definition of level curves, if we are given a function of two variables z = f (x, y),the crosssection between the surface and a horizontal plane is called a level curve or a contour curve Thus, level curves have algebraic equations of the form f (x, y) = k for all possible values of k
