I typed up this set of instructions for finding the y-intercept of a graph using the TI-84 for my Algebra 2 students to fill in and glue in their interactive notebooks.

I included instructions for two different ways that students could find the y-intercept of a graph using their graphing calculator.

Giving students multiple solving options is something I’m trying to do a better job of incorporating in my classes.

## Finding the Y-Intercept Using the Table Function on the TI-84 Calculator

- Enter the equation in Y1
- Open the table function on your calculator (
**2ND GRAPH**) - Find the line on the table where x is 0

## Finding the Y-Intercept Using the Graph Function on the TI-84 Calculator

- Enter the equation in Y1
- Open the graph
- Open the calculate function on your calculator (
**2ND TRACE**) - Select
**Option 1: VALUE** - Specify that you want to find the value when x is 0

I also created a separate set of instructions for finding x-intercepts of a graph using the TI-84 graphing calculator.
