Co-ordinates & Linear Graphs
Help!

|---|---|---|---|---|---|
| Coordinates | Describe a position on the Cartesian Plane.
🗑
|
||||
| Origin | Where the x and y axis intersect.
The coordinates are (0,0)
🗑
|
||||
| x- axis | x- axis is the horizontal axis
🗑
|
||||
| y-axis | y-axis is the vertical axis
🗑
|
||||
| Coordinates are written as | (x,y)
🗑
|
||||
| Alphanumeric | grid references for a map
Letter number
🗑
|
||||
| Cartesian Plane | Describes the location on a plane by using two numbers as coordinates
🗑
|
||||
| Quadrants | The axes dividing the Cartesian Plane into four sections
🗑
|
||||
| Linear Pattern | Patterns forms a straight line
🗑
|
||||
| Non Linear Pattern | Patterns do not form a straight line.
🗑
|
||||
| Linear functions | Linear rules
f(x)=
🗑
|
||||
| Gradient | Measure of steepness
🗑
|
||||
| Gradient formula is....... | m=rise/run
🗑
|
||||
| Rise..... | Is the vertical distance between any two point on the line
🗑
|
||||
| Run..... | Is the horizontal distance
🗑
|
||||
| y-intercept | Is the y-intercept of the point where the graph crosses the y-axis.
🗑
|
||||
| Rule for all Linear graphs is...... | y=mx + c
🗑
|
||||
| In the rule for all Linear graphs the 'm' is y=mx + c | The 'm' is the gradient
🗑
|
||||
| In the rule for all Linear graphs the 'c' is y=mx + c | The 'c' is the y-intercept
🗑
|
||||
| In the rule for all Linear graphs the 'y & x' is y=mx + c | The 'y & x' are the variables
🗑
|
||||
| When sketching linear graphs | Only two point are needed
🗑
|
||||
| When two graphs intersect..... | The two equations share the same x and y coordinates.
This point is the solution to the two equations.
🗑
|

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
