Demand curves almost always have negative slopes. The Y value being price and the X value being quantity. The higher the price, the more negative the slope. There are very rare conditions where a demand curve could have a positive slope, but its not normally used in business classes.

Can slope k of a direct variation be positive?
The slope of the graph of a direct variation is always positive.
Is a horizontal slope always positive?
No, never.
When a pair of variables have a positive correlation will the slope in the regression equation always be positive?
Yes
How do you trace a curve in differential calculus?
To trace a curve using differential calculus, you use the fact that the first derivative of the function is the slope of the curve, and the second derivative is the slope of the first derivative. What this means is that the zeros (roots) of the first derivative give the extrema (max or min) or an inflection point of the function. Evaluating the first derivative function at either side of the zero will tell you whether it is a min/max or inflection point (i.e. if the first derivative is negative on the left of the zero and positive on the right, then the curve has a negative slope, then a min, then a positive slope). The second derivative will tell you if the curve is concave up or concave down by evaluating if the second derivative function is positive or negative before and after extrema.
How the slope of a curved line at a point can be found?
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.
Which direction does the demand curve slope?
Is always negative. (should be in all caps for emphasis)
How does the principle of diminishing marginal utility explain the slope of the demand curve?
The principle of diminishing marginal utility explains the slope of the demand curve by letting us be able to see which direction the slope is in, which is always downward.
Is the price elasticity constant along the demand curve?
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.
What is difference between slope and the calculation of elasticity for a linear demand curve?
Along a linear demand curve elasticity varies from point to point of the demand curve with respect to different price, but slope is constant
What is the typical slope of a demand curve?
Downward
Is demand curve canbe upwardly sloping?
A demand curve can have an upwards slope. It solely depends on if the demand for an item is high or low.
How can one calculate marginal revenue from a demand curve?
To calculate marginal revenue from a demand curve, you can find the slope of the demand curve at a specific quantity using calculus or by taking the first derivative of the demand function. The marginal revenue is then equal to the price at that quantity minus the slope of the demand curve multiplied by the quantity.
Demand curve slopes downwards from left to right. this is the negative slope that shows the inverse relationship between price and demand. explain why does the demand curve slope downwards?
because demand decreases as price increases :)
Why does the LM curve have a positive slope?
The LM curve has a positive slope because as interest rates increase, the quantity of money demanded decreases. This is because higher interest rates make borrowing more expensive, leading to a decrease in investment and consumption, which in turn reduces the demand for money.
What is the paradoxical demand curve?
Paradoxical demand curve is a theory that the slope of a product will change a different times. This is called Griffin's Paradox.
Why does a demand curve slope downward left to right?
A demand curve slopes downward left to right because the relationship between price and demand is negative - as price drops demand rises. The opposite is true for a supply curve where as price rises supply rises - the relationship is positive so the supply curve slopes upward from left to right. Nova net answer- because demand decreases as price increases
