Why Demand curve slopes downward

The relation between the slope of isothemal curve and slope of adiabatic curve

DeltaG^(Ө) vs T plot in Ellingham diagram slopes downward for the reaction .

Show that the slope of adiabatic curve at any point is Yama times the slope of an isothermal curve at the corresponding point.

For a p-V plot, the slope of an adiabatic curve = x × slope of isothermal at the same point. Here x is :

At any point (x,y) of a curve, the slope of the tangent is twice the slope of the line segment joining the point of contact to the point (−4,−3). Find the equation of the curve given that it passes through (−2,1)

At any point (x, y) of a curve, the slope of the tangent is twice the slope of the line segment joining the point of contact to the point (" "4," "3) . Find the equation of the curve given that it passes through (2," "1) .

At any point (x, y) of a curve, the slope of the tangent is twice the slope of the line segment joining the point of contact to the point ("-"4,"-"3) . Find the equation of the curve given that it passes through (2,"-"1) .
