2. J. A Shortcut
1. Enter data.
2. Graph it.
3. [Stat] [Calc] [A:PwrReg]
4. [2nd] [List] ‘T’ [,]
5. [2nd] [List] ‘D’ [Enter]

5. J. A Shortcut
5. On screen we see:
a. PwrReg
y = a*x^b
a = 28
b = 1

7. J. A Shortcut
y = a*x^b
Starting with:
Substituting 28 m/s for a and 1 for b, one gets:
Replacing ‘y’ with ‘D’ and ‘x’ with ‘T’ one gets the equation:

y = a*x^b
a = 20
b = 2

14. y = a*x^b M. The Equation is:
Substituting 20 m/s2 for ‘a’ and ‘2’ for ‘b’.
Replacing ‘y’ with ‘D’ and ‘x’ with ‘T’ one gets the equation:
