Day 2: Visual

Day 2: Students will write a linear equation using data from a line of best fit or given 2 data points

Linear Equation Formula : Y=mx+b ,  m=slope,

Another Example ^

1. plug your Y from the data point and your X from the data point, then add the slope in. For example: if you have (8,1)
(-2,3) .. your slope will be  1 
                                         -5 

2. Pick one set of data points to work with now. 

3. I chose (8,1) . My equation would be 1= 1 (8)+b
                                                                  -5
