Algebraic Notation Scenario (1) P-2 If the x co-ordinates for all the points are increased by three how could we describe this?

Algebraic Notation Scenario (1) P-3 If the x co-ordinates for all the points are increased by three how could we describe this?

Algebraic Notation Scenario (2) P-4 If both the x and y co-ordinates are doubled how could we describe this?

Algebraic Notation Scenario (2) P-5 If both the x and y co-ordinates are doubled how could we describe this?

Directions for today: Each of the transformation cards show two out of a possible four pieces of information: 1.A transformation described using algebraic notation. 2.A transformation described in words 3.The original figure before applying the transformation (i.e. the pre-image) 4.The transformed image Your job is to complete all the missing information on each of the cards. Tomorrow we will group the cards depending on whether they describe rotations, reflections or translations. P-6
