Coordinates, Sequences and Graphs Summary

Coordinates, Sequences and Graphs

Summary

numbers are often arranged in order, called a sequence.sequences often follow a rule or pattern.

a number plane or cartesian graph consists of two number lines at right angles called the x-axis and the y-axis.

position on the number plane is fixed by a pair of coordinates (x, y)

there are many types of graphs ranging from line graphs through to statistical graphs.

Key Skills
  • given a sequence, find the missing numbers
  • find the formula or the rule which describes the sequence
  • locate a point on a number plane given its coordinates
  • give the coordinates of a point on a number plane
  • draw the graph of a sequence
  • read information from graphs
  • draw graphs from given information
