WILF
To be able to calculate x and y values for an equation and then plot it on a graph using a table – Grade E/D
Key Words equation axis x value y value coefficient gradient intercept constant

2. What can you tell me about this equation?
x+y = 10
On your whiteboard, write down 5 sets of co-ordinates which satisfy the equation
(1 min)
x+y = 10

using a table

5. y = 3x -2 x 1 2 3

6. y = 3x -2 x 1 2 3 3x 3 6 9

7. 3x -2 x 1 2 3 3x 3 6 9
Remember -2 is constant -2 -2 -2 -2 -2

8. y = 3x -2 x 1 2 3 3x 3 6 9
Remember -2 is constant -2 -2 -2 -2 -2
y=3x-2 -2 1 4 7

9. y = 4x +3 x -1 1 2 3

10. y = 4x +3 x -1 1 2 3 4x -4 4 8 12

11. 4x +3 x -1 1 2 3 4x -4 3 6 9
Remember +3 is constant +3 +3 +3 +3 +3 +3

12. y = 4x +3 x -1 1 2 3 4x -4 3 6 9
Remember +3 is constant +3 +3 +3 +3 +3 +3
y=4x+3 -1 3 6 9 12
