1. T-Tables & Scatterplots

2. Hand out homework worksheet.
Goals: #1 - Students will be able to create a t-chart given an equation of a line. #2 - Students will be able to graph a line by creating a t-chart, plotting the points, and connecting them to form a line. #3 – Students will be able to identify different types of correlation, positive, negative & none.

Graphing Lines.
You must graph 10 lines using the given equations and create a t-table that correspond with that.
Name _________________ Date______________ Period_____________
y = 2x + 1
y = -2x + 2 x y x y
y = 3x + 1
y = 2x x y x y

14. Graphing Lines. x y x y x y x y y = x y= x + 1 y= -x - 2 y= 2x - 1
You must graph 10 lines using the given equations and create a t-table that correspond with that.
y = x
y= x + 1 x y x y
y= -x - 2
y= 2x - 1 x y x y
