Calculate the slope of a line that has a Rise of 3 and a Run of 6.
3/6 or 1/2 or 0.5
What is the Dependent Variable?
What you measure in the experiment
Describe a situation where you'd use a meterstick verses a ruler?
Meter stick is for larger things, ruler is for smaller items

What is the equation of a line?
y=mx + b
Calculate the slope of a line, where two points on the line are (3,8) and (7,16)
Rise: 8 (16-8) Run:4 (7-3)
Slope= Rise/Run = 8/4
Slope=2
