Weds 5th OCT – Sketching Inequalities on a graph

LEARNING OBJECTIVE: Practise sketching inequalities on a coordinate grid

SUCCESS CRITERIA: You will be able to sketch straight lines on a graph and determine which side of the line represents the region of the inequality

STARTER: Plot the following lines on a coordinate grid:

Y = 2x +3	Y = 3x – 1	Y = 2x +5	Y = -2x -3
2y = 4x +8	2y-6x = 10	10x - 5y = 20	4y + 6x = 10

 
 

Discuss plotting the points to revise y = mx + c work and quickly plotting a straight line on a graph

LESSON: Watch this video on deciding which side to shade.

Now continue to work through the questions on this worksheet.
