Price level is graphed on the Y-axis and RGDP is graphed on the X-axis, both are increasing away from the origin. When price level is higher RGDP is lower, (stuff is more expensive so people buy less). When price level is lower, RGDP increases.
The Real Wealth Effect: a fixed amount of wealth will lose purchasing power if prices go up, consumption will decrease
The Interest Rate Effect: Higher price levels create a greater demand for money, this causes interest rates to go up which causes investment to go down, which affects the Aggregate Demand
The Open Economy Effect: if it is cheaper to buy a product from a different country, consumers will do so. This affects Net Exports.

As war is an unexpected factor that impedes the economic growth of a country, it leaves the aggregate demand with no option but a slope negatively downwards in dicating higher price levels.
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.
Along a linear demand curve elasticity varies from point to point of the demand curve with respect to different price, but slope is constant
Downward

Is always negative. (should be in all caps for emphasis)
A demand curve can have an upwards slope. It solely depends on if the demand for an item is high or low.
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.
because demand decreases as price increases :)
The demand curve is negatively sloped because it is based on the principle of marginal utility and this utility decreases as consumption increases. The demand price which depends on the marginal utility of a good also declines as consumption increases, so quantity and price are inversely related, leading to the negative curve and the law of demand.
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.
Paradoxical demand curve is a theory that the slope of a product will change a different times. This is called Griffin's Paradox.
