Explanation Given information: A contour plot, Consider the contour plot of the function f ( x , y ) . Since the contour lines are horizontal lines thus, the contour plot is a plot of straight lines parallel to y axis To determine (b) If f x ( A ) is positive, negative or zero. To determine (c) If f y ( A ) is positive, negative or zero.

Rate of Change

The relation between two quantities which displays how much greater one quantity is than another is called ratio.

Slope

The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:
