NettetLinear Function. A linear function is a function whose graph is a line. Linear functions can be written in the slope-intercept form of a line. f(x) = mx + b. where b is the initial or starting value of the function (when input, x = 0 ), and m is the constant rate of change, or slope of the function. The y -intercept is at (0, b). NettetZero slope refers to a line parallel to the x-axis of the coordinate system. The line with zero slope makes an angle of 0º or 180º with the positive direction of the x-axis. Any … NettetInstructions: On the interactive graph, there are a red and blue dots.

NettetA linear relationship describes a relation between two distinct variables – x and y in the form of a straight line on a graph. When presenting a linear relationship through an equation, the value of y is derived through the value of x, reflecting their correlation. Linear relationships apply in day-to-day situations where one factor relies on ... NettetThe least squares estimates of the regression coefficients, b 0 and b 1, describing the relationship between BMI and HDL cholesterol are as follows: b 0 = 111.77 and b 1 = -2.35.
