1. Plotting coordinates into your TI 84 Plus Calculator

2. Steps 1. 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 L2 3. Run the linear regression by pressing Stat, then going to CALC, select 4 (LinReg) and Enter You should see

3. 4. Plot this graph by entering the slope y intercept form How? a)Press Y= key b)Type equation and press Enter. 5.Press Graph. 6.Check coordinates on a Table. How? a)Press 2 nd button and Graph

4. Trouble shoot Can’t see L2 for entering y coordinates. Solution: Press Stat, 5(Setup Editor), Enter.
