The phrase "a linear fall" is correct and usable in written English.
It can be used to describe a decrease or decline that follows a straight or consistent path, often in contexts like mathematics, physics, or economics.
Example: "The graph illustrates a linear fall in temperature over the course of the day."
Alternatives: "a steady decline" or "a straight decrease".
The H/C ratio plotted against aromaticity shows a linear fall, confirming the graphitization of coal on leaching (Fig. 6).
The tone of the first syllable vocalic nucleus was set to two different levels: a straight linear (high) tone throughout the vowel or a linear fall.
The pitch trajectory of the first syllable was either set at 230 Hz or a linear fall from 230 Hz to 150 Hz was inserted.

The short spoken member of the pair (sika "pig") was recorded and manipulated: the duration of the first syllable was set to either 110 (short) or 135 (long) milliseconds with either a level (high) or a linear falling (fall) tone.
A finite element model based on the actual 3D cell structure of the aluminium foam imaged by X-ray computed tomography (CT) predicts an approximately linear fall of elastic modulus from zero strain until a band of collapsed cells forms.
Figure 3 shows the linear fall in product AMW over reaction time, consistent with preferential degradation of higher hydrocarbons.
For CAD-silenced straw the graph showed clear linear fall in first 14 days and then the strongest drop was observed between 14th and 17th day.
A modified CDC model incorporating a convex falling rate produced better agreement than the conventional linear falling rate model.
Spectra generated by Galactic Cosmic Rays (GCR) protons and their secondaries are with linear falling shape in the coordinates deposited energy/deposited per channel dose rate.
We used a previously developed technique in which the options above 1 % fell on a linear scale and the options below 1%% fell on a roughly log scale (Woloshin, Schwartz, Byram, Fischhoff, and Welch, 2000).
