Price elasticity of demand is equal to the instantaneous slope of the demand curve, or the slope of the tangent line at any point on the demand curve. So if the demand curve is represented by a straight downward sloping line, then yes, price elasticity of demand is equal to the slope of the demand curve. Otherwise, the slope at any point on the curve is changing, and you can find the it by taking the derivative of the demand curve function, which will find the Price elasticity of demand at any single point. Thus, the Price Elasticity of Demand changes at different points on the demand curve.
Supply curves do not always slope from left to right. A supply curve can slope from the right and when this happens this means that there is a surplus of goods at a lower price.
mainly the slope of Is curve depends on ; -the slope of investment schedule -the size of the multiplier
Slope of a Curve A number which is used to indicate the steepness of a curve at a particular point.The slope of a curve at a point is defined to be the slope of the tangent line. Thus the slope of a curve at a point is found using the derivative
You find the tangent to the curve at the point of interest and then find the slope of the tangent.
It bend and forms a curve.
The gradient of the tangents to the curve.

A horizontal line has a slope of zero. Also, a curve on its lowest and highest points (local maxima or local minima) normally has a slope of zero at such a point.
You find the slope of the tangent to the curve at the point of interest.

If the curve is on the xy-plane, finding an expression for dy/dx will give you the slope of a curve at a point.
You find the tangent to the curve at the point of interest and then find the slope of the tangent.
The slope of a curved line at a point is the slope of the tangent to the curve at that point. If you know the equation of the curve and the curve is well behaved, you can find the derivative of the equation of the curve. The value of the derivative, at the point in question, is the slope of the curved line at that point.
Marginal Revenue is the derivate (rate of change) of total revenue. Total revenue is = Price x Quantity. For instance, if the demand curve was Q = 100 - P, find the inverse demand (P = 100 - Q). Total Revenue = 100Q-Q^2Therefore marginal revenue is the derivative of 100Q - Q^2.MR = 100 - 2Q (thus twice the negative slope).In short: inverse demand x Q, find the derivative.Source(s):Microeconomic Theory Class
