- Straight Line Graphs
- Examples of equations on straight lines
- x=y
- 2y-3x=7
- y=-1
- y=3x=2
- x=7
- x=2

- Can contain
- an x term
- a number
- but it might only contain 2
- a y term

- Make a table
- of x and why numbers
- and work out the coordinates
- of x and why numbers

- Then plot the points.
- and work out the coordinates

- and work out the coordinates
- Join up the points
- Then plot the points.

- Then plot the points.

- Finding the gradient
- Choose any 2 points on the line
- draw a right-angled triangle with the line as hypotenuse
- find the triangle's...
- vertical length
- and horizontal length
- vertical length÷hotal length

- and horizontal length

- vertical length

- find the triangle's...
