By the end of the lesson (PowerPoint) you should
1. be able to draw a straight line graph using a table of values
2. be able to understand the words ‘gradient’ and ‘y-intercept’
(gradient - slope: negative and/or positive)
For USA - substitute 'c' with 'b' - both in essence mean the same thing. You will be able to adapt the PowerPoint accordingly ...
Concepts: Coordinates; axes; equation
Numerous examples followed by completing a table, recognising the points to be plotted as well as then being able to complete the straight line requested from a given equation.
Extension questions followed by a homework/prep task that could also be utilised as a test.
