its zero
I'll do a bit of the explanation:
Price Elasticity of Demand captures the shift in demand for rises in prices in percentage terms. Therefore if a commodity is such that no matter what price the producer charges the consumer has no alternative but to buy it, then for any price the demand for that commodity remains unaltered, maybe an example is a monopolist salt producer. Therefore the demand curve must be vertical, no matter what the price the quantity demanded is same, hence the price elasticity is zero.

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.
Is price elasticity constant along demand curves?
explain why the price elasticity of demand varies along a demand curve, even if the demand curve is linear.
Explain the difference between price elasticity of demand and the slope of a demand curve?
Price elasticity is a specific type of slope of the demand curve. A perfectly inelastic demand means that the quantity will not change with the price. This line is perfectly vertical. A perfectly elastic demand curve is horizontal and means that at any given quantity, there is only one price. Also, a slope gets steeper, demand becomes more inelastic.
Explain the difference between elasticity of demand and the slope of a demand curve?
The demand curve is drawn with price on the vertical axis and quantity demanded on the horizontal axis. Mathematically, the slope of a curve is represented by rise over run, or the change in the variable on the vertical axis divided by the change in the variable on the horizontal axis. Therefore, the slope of the demand curve represents change in price divided by change in quantity. Elasticity, on the other hand, aims to quantify the responsiveness of demand and supply to changes in price, income, or other determinants of demand.
3 Why is it difficult to judge the price elasticity of demand if you are merely observing the appearance of a demand curve on a graph?
Because elasticity is changes depending on the price it is evaluated at. This will then mean that elasticity is different at different point on a demand curve. It can also depend on the scale the demand curve is drawn to

Why is the demand curve not representative of price elasticity?
price elasticities are always negative hence brings ambiguities in 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 elasticity of vertical and horizontal demand line and why is it horizontal or vertical?
Although I have never taken an economics class discussing the formal definition of demand elasticity, I can guess at the answers. Elasticity is a measure of how much the quantity demanded of some product is swayed by changes in price. Economists traditionally place prices on the y-axis and quantity demanded on the x-axis. So if the demand curve is a vertical line, it means that no matter what the price is, customers will keep buying the same amount. This suggests that the elasticity is zero. The horizontal demand line is less meaningful because it shows one price at which customers may demand anything, while if the price is raised ever so slightly, we will fly off the demand curve altogether. Since tiny or even zero changes in price can cause large changes in demand, the elasticity is probably either infinite or undefined.
What does the demand curve state?
As price (on the horizontal) increases, demand (on the vertical) will decrease.
How is price elasticity of demand measured on a particular point on a negatively sloped demand curve?
point method
How does a change in price on a linear demand curve affect total revenue?
on the linear demand curve, demand is elastic at price above the point of unitary elasticity so a price increase will decrease the total revenue.
