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 ... WebFor simple linear regression, the least squares estimates of the model parameters β 0 and β 1 are denoted b0 and b1. Using these estimates, an estimated regression equation is constructed: ŷ = b0 + b1x . The graph of the estimated regression equation for simple linear regression is a straight line approximation to the relationship between y ...
WebSlope is the change in y/change in x; the same thing as rise/run. Here is an example: Lets say you have a equation that says y=1/4x+2. Its pretty simple from there. So, we know in the slope intercept formula (y=mx+b) we know that m=slope and b=y intercept. So for the equation I gave you m=1/4 and b=2. So, from the y-intercept (which is 2) you ...
