Plotting coordinates into your TI 84 Plus Calculator

Steps1. Find a least two points from a graph, table or two sets of coordinates and put them in a Table. (2,4) (-7, 8)2. Place the x coordinates under L1 and y coordinates under L2.

How? a) Press Stat , Enter. b) Type in x coordinates under L1, type y coordinates under L23. Run the linear regression by pressing Stat, then going to CALC, select 4 (LinReg) and Enter You should see

4. Plot this graph by entering the slope y intercept form How?a) Press Y= keyb) Type equation and press Enter.

5. Press Graph.6. Check coordinates on a Table. How?a) Press 2nd button and Graph

Trouble shoot

Can’t see L2 for entering y coordinates.

Solution:Press Stat, 5(Setup Editor), Enter.
