How do you find line of best fit on a calculator?
Finding the Line of Best Fit (Regression Analysis).
- Press the STAT key again.
- Use the TI-84 Plus right arrow to select CALC.
- Use the TI-84 Plus down arrow to select 4: LinReg (ax+b) and press ENTER on the TI-84 Plus, and the calculator announces that you are there and at Xlist: L1.
How do you find the line of best fit on a calculator?
The line of best fit is described by the equation ŷ = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Y when X = 0). This calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X.
How do you plot points on a graphing calculator?

How do I plot points on a graph?
To graph a point, first locate its position on the x-axis, then find its location on the y-axis, and finally plot where these meet. The center point of the graph is called the origin and is written as the point (0, 0) because it’s located at the zero point on the x-axis and the zero point on the y-axis.
