Best fit graphs

Best fit graphs

1. Good practice

   • Title
   • Labelled axes
   • SI units
   • Straight lines
   • Reasonable divisions

2. Gradient

   • Rise over run
   • Y2 - y1 over x2 - x1
   • Include units

3. Intercept - point at which line of best fit meets y axis vertical

4. Equation for Straight line

   • Y= mx + c
   • m = gradient (mountain)
   • C = interCept
   • Can also be written as b= mA +c
