The least squares regression line was computed in "Example 10.4.2 " and is ˆy = 0.34375x − 0.125. SSE was found at the end of that example using the definition ∑ (y − ˆy)2. The computations were tabulated in Table 10.4.2. SSE is the sum of the numbers in the last column, which is 0.75.23.1 Simple Linear Regression. We begin by demonstrating the LinRegTTest feature (item E) from the STAT TESTS menu that will compute a least-squares regression line while simultaneously testing the null hypothesis that the regression slope (and correlation) equals 0.

IB Math Video - Using a TI-84 for the line regression model.In summary, if y = mx + b, then m is the slope and b is the y-intercept (i.e., the value of y when x = 0). Often linear equations are written in standard form with integer coefficients (Ax + By = C). Such relationships must be converted into slope-intercept form (y = mx + b) for easy use on the graphing calculator.One other form of an equation for a line is called the point-slope form and is ...You can draw a line in the xy-plane: say y = ax + b.
