We use substitution to calculate the values. We replace the value of x for different numbers and record the resulting y value. These coordinates can then be plotted on a graph. Step 1 – The x ...
All the coordinates have equal values for \(x\) and \(y\). This is shown by the points on the line such as (10, 10) and (-4, -4). Graph A is \(y = -x\). All the coordinates have \(x\) and \(y ...
At the time of introducing coordinates, North and East are positive, with their value in degrees (with decimals). Some point you can test are: Madrid 40N 6W, Tokyo: 35N 139E, Chile 33S 70W. The ...
