Equation of a Straight Line (Algebraic Substitution) - Maths GCSE PowerPoint & ActivInspire Lesson

Maths GCSE lesson on forming an equation of a straight line through algebraic substitution (given the gradient and a point the line passes through).

Please note this is five of five lessons on equations of straight lines:

1. Finding gradient and y-intercept both from the graph and by inspecting the equation
2. Sketching the equation of a straight line using the gradient and y-intercept
3. Plotting equations of a straight line using a table of values
4. Finding the midpoint of a line segment
   5) Finding the equation of a straight line using algebraic substitution

Lesson structure includes examples, MWB section, two tasks and a challenge task.

PowerPoint and ActivInspire formats included.
