Quizplus · Accepted Answer

The equation X * Z = 10 represents a level curve or a contour line since it indicates all the values of X and Z that give the same output for Y. It does not represent the X-intercept or Y-intercept since there is no reference to Y in the equation. It also does not represent a tangent line.
