Find Y coordinate for a specified X coordinate on a linear function determined by two points.
Input
Fist point X coordinate
$ x_1 = -0.0385 \; \; $
First point Y coordinate
$ y_1 = 3.7 \; \; $
Second point X coordinate
$ x_2 = 0.0025 \; \; $
Second point Y coordinate
$ y_2 = 2.1 \; \; $
X coordinate
$ X = -0.017 \; \; $
Result
Y coordinate
$$ Y_{LI} = {y_1 + {\left({ y_2 - y_1 }\right) \over \left({ x_2 - x_1 }\right)} \cdot \left({ X - x_1 }\right)} $$
