Weds 14th Sep – Mid-point of a line segment, Lines between two given points and parallel Lines

LEARNING OBJECTIVE: Establish a method for finding the midpoint of a line segment, deriving the equation of a line given two points on the line and find the equation of parallel lines.

SUCCESS CRITERIA: You will be able to:

1. Find the midpoint of a line segment
   
2. Work out the equation of a line given two points on the line
   
3. Work out the equation of a parallel line given the equation of a line and a coordinate on the parallel line.
   

STARTER: Can you match the equations to the lines

 
 

LESSON: Explore on the IWB finding the mid point of a line segment
