The slope is -2.326, the speed of sound in knots decreases by 2.326 knots per thousand feets.

Linear equation

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the y intercept.

Let y represent the speed of sound in knots at x thousand feets.

y = -2.326x + 661.9

The slope is -2.326, the speed of sound in knots decreases by 2.326 knots per thousand feets.

The y-intercept represents the speed of sound of 661.9 knots at 0 feet.
