Lesson Six

WARM UP

Today’s warm up will be done and handed in for a grade.

You have ten minutes to complete this warm up.

Today you will become familiar with the graphing calculator. You will spend the next 20 minutes working through a scavenger hunt. You will need to record your answers in the spaces provided. Work with a partner.

We can use the graphing calculator to find the equation of a line.

Watch this short video.

Copy down the steps on the next slide so that you can reference them when you are practicing.

• stat

• edit (1)

• type in ordered pairs

• stat – calculate

• scroll to 4

• calculate

• y = ax + b (a =? b = ?)

Use these steps to help you write the equation of a line.

Let’s use the following and find the equations of the line (function rule).
