Coordinate Geometry: Line Intercepts and Triangle Area
Coordinate Geometry: Line Intercepts and Triangle Area
Secondary 3
The diagram shows the graph of \(y=8-x\).
The graph intersects the \(x\)-axis and \(y\)-axis at points \(A\) and \(B\) respectively.
- Write down the coordinates of \(A\) and \(B\).
- Calculate the length of the line segment \(AB\).
- Calculate the area of triangle \(AOB\).
Hence, calculate the shortest distance from point \(O\) to the line \(AB\).
