Yr 7 Linear Equation
Linear Equations & Cartesian Plane
Term | Definition |
---|---|
Equation | A number problem with an equal sign |
To solve an equation | Means find the value of the pronumeral |
Pronumeral | A lower case letter used to represent an unknown number |
Expression | Does not have an equal sign |
Trail & Error | Guess & Check |
Inspection | To look at, examine carefully |
Inverse Operations | Doing the opposite operation |
The inverse operation to Addition | Subtraction |
The inverse operation to Subtraction | Addition |
The inverse operation to Multiplication | Division |
The inverse operation to Division | Multiplication |
Input | The first number or pronumeral in a flowchart |
Output | The last number or pronumeral in a flowchart |
Backtracking | Working backwards, used to find the Input number 'underneath' the flowchart using inverse operations |
Alphanumerical grid/area reference | Letter & Number co-ordinates used on maps Capital letter No comma or brackets required |
Cartesian Plane | Formed by two Perpendicular lines Using (x,y) coordinates |
Quadrants | The axis divide the Cartesian plane into four sections called quadrants. Quadrants are numbered in an anti clockwise direction, starting with the top right |
The x-Coordinate | the x -coordinate always comes first running along the x axis |
The y- Coordinate | The y -coordinate always comes second, running along the y axix |
Coordinates | (x,y) give the directions of a point |
Linear Pattern | A set of points forming a straight line on the Cartesian plane |
