## Unit 14 Section 1 : Coordinates
You will have used coordinates before. In this section, we revisit coordinates before starting work on lines and graphs.
The origin is the centre of the graph at ( 0 , 0 ).
## Practice QuestionWork out the answer to each of these questions then click on the button marked to see whether you are correct.Look at the coordinate grid below.
## ExercisesWork out the answers to the questions below and fill in the boxes. Click on the button to find out whether you have answered correctly. If you are right then will appear and you should move on to the next question. If appears then your answer is wrong. Click on to clear your original answer and have another go.

Question 2(a) Plot these points on the graph below and join them up with straight lines to form a triangle: ( 3 , –2 ) , ( –1 , 6 ) and ( –5 , –2 )
Question 3(a) Plot these points on the graph below and join them up in order to form a shape: ( –1 , 4 ) , ( 2 , 5 ) , ( 5 , 4 ) and ( 2 , –1 )
Question 6A shape has corners at the points with coordinates: ( 3 , –2 ) , ( 6 , 2 ) , ( –2 , 2 ) and ( –5 , –2 ).
(a) Plot the points on the graph below and join them in order. Question 7A shape has corners at the points with coordinates: ( 3 , 3 ) , ( 1, –1 ) , ( 3 , –5 ) and ( 5 , –1 ).
