Thurs 8th Sep: Methods for quickly finding three cords from a Linear Equation and then draw the line on a graph

LEARNING OBJECTIVE: To recognise a linear equation and draw the straight line graph that represents it

SUCCESS CRITERIA: You will be able to find at least three coordinates form any linear equation that will enable you to draw the straight line that represents the equation

RULE: You can spot a linear equation as it will NOT have any squared or cubed letters in it.

BE CAREFUL IF a function has brackets in it YOU MUST expand the brackets first before applying the above rule (Give and example on IWB to demonstrate)

STARTER:

For each of these linear equations complete the table of x and y values and then draw the line

Y = 3x + 2 X 0 1 2 Y	Y = ¼x +4 X 0 1 2 Y
2x + 3y = 9 X 0   3 Y   0	4x – 5y = 20 X 0     Y   0 1

LESSON: Use answers to above starter to reinforce how to quickly find three coordinates from a linear equation

Continue from yesterday these questions

PLENARY: Checking Answers. Quickly find three cords for these two equations and sketch them

Y = 5x + 2, 3x + 2y = 12
