The description can help to form a simple data table for two linear points.

x y 1.5 94 1.5+2.5 94-42

These are points, (1.5,94) and (3,52).

A neat way to setup the equation is to use both formula for slope and the linear equation in point-slope form using the second point:

Simplify from there into general form.
