Web16 jul. 2024 · A linear regression line can be represented using the equation of a straight line: y = mx + b In this simple linear regression equation: y is the estimated dependant variable (or the output) m is the regression coefficient (or the slope) x is the independent variable (or the input) b is the constant (or the y-intercept) WebEquation for a Line. Think back to algebra and the equation for a line: y = mx + b. In the equation for a line, Y = the vertical value. M = slope (rise/run). X = the horizontal value. B = the value of Y when X = 0 (i.e., y-intercept). So, if the slope is 3, then as X increases by 1, Y increases by 1 X 3 = 3. Conversely, if the slope is -3, then ...
