The main part of this PowerPoint is 16 slides , it begins with the calculation on a table of values to satisfy an equation and plotting the coordinate pairs on axes. The third example of this has negative slope. Next graphing by gradient is explained for both positive and negative lines. Then another example is included before 2 questions (1 positive, 1 negative).
Finding the equation of a given line is introduced and 8 graph lines are shown for which equations are to be found. Then 6 given equations require the graphs drawing, and 4 more lines need equations to be found.
A given graph converts speed Kph to Mph with 4 values to be identified.
The last 2 slides consider scatter graphs and lines of best fit.
At the end of the presentation are 7 additional slides with grid lines and axes to use as you wish, these are also included as a worksheet if you choose to use it.
