The phrase "a decreasing slope" is correct and usable in written English.
It can be used in contexts related to mathematics, physics, or any discussion involving graphs or trends where a decline is observed.
Example: "The graph shows a decreasing slope, indicating a decline in sales over the past year."
Alternatives: "a downward slope" or "a negative slope".
During the E2 d 2 period, the Gaoyou Depression was characterized by weak movement of faults and basement uplift, resulted in a shallowing water depth, a decreasing slope gradient, and disappearance of nearshore subaqueous fans in the southern slope (Figs. 9d, 10).
Statin use posttransplant was associated with a decreasing slope of change in common carotid IMT.
The joinpoint analysis relative to male lung cancer mortality indicates a decreasing slope after 1989.
This correlation is therefore not linear but shows a decreasing slope with higher SR.
Mixed inhibition was also observed for compound 2, indicated by a decreasing slope with an increasing inhibitor concentration.
For successive positions the SSW monotonically decreases with a decreasing slope becoming almost flat at the end.
As shown in Fig. S4, the BiVO4 film prepared with NaCl shows a decreased slope, which indicates the rapid increase in N d.
It is found that a decrease slope efficiency is resulted when the indium content of InxGa1-xN quantum barrier (QB) layers is higher than about 1%, which is caused by the significantly increase of electron leakage current due to the piezoelectric polarization effect in high indium content InxGa1-xN last QB (LQB) layer.
Since physical activity energy expenditure is proportional to body weight, decreased physical activity would result in a decreased slope of the relationship between energy expenditure versus weight change.
Increased AAG resulted in a decreased Slope value.
We found a decreased slope of the EA– NA relationship when 200 taxonomically closely related willow genotypes with variable NA were exposed to a water-stress treatment.
