Quizplus · Accepted Answer

Regression analysis of two methods proven to correlate produces a line described by an equation that takes the form y = a + bx, where y and x are comparative results by the two methods, a is the y-intercept, and b is the slope of the line described by the equation.It is the slope, b, that describes the proportionality between the two methods.An ideal value for the slope is b = 1, which would indicate there is no proportionality error between the two methods.For y = 0.137 + 0.813x, the slope is 0.813.
