## Plotting coordinates into your TI 84 Plus Calculator

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

4. Plot this graph by entering the slope y intercept form

How?

Press Y= key

Type equation and press Enter.

Press Graph.

Check coordinates on a Table.

How?

Press 2nd button and Graph

Trouble shoot

Can’t see L2 for entering y coordinates.

Solution:

Press Stat, 5(Setup Editor), Enter.
