The slope of the budget line represents the amount of good "y" the consumer must give up to purchase one more unit of a good "x." The budget line itself represents the number of good bundles a consumer can buy with limit...

In the Cartesian Plane, the slope of a graph represents the rate of change of the graph. The slope of graph at any given point is the point's "y" value (rise) divided by the "x" value (run).

A tangent is a line that intersects a curve at only one point and does not pass through it, such that its slope is equal to the curve's slope at that point. To find a horizontal tangent, you must find a point at which th...

To find the slope of the tangent line to the graph of a function at a point, find the derivative of the function, then plug in the x-value of the point. Completing the calculation takes just a few minutes by hand, or a c...

The formula for finding the slope of a line on a coordinate plane is (y2 - y1) / (x2 - x1), where (x2, y2) and (x1, y1) represent two distinct points on the line. This is also known as "change in y over change in x" or "...

Find the equation for the tangent line to a curve by finding the derivative of the equation for the curve, then using that equation to find the slope of the tangent line at a given point. Finding the equation for the tan...

The average rate of change in calculus refers to the slope of a secant line that connects two points. In calculus, this equation often involves functions, as opposed to simple points on a graph, as is common in algebraic...
