A co ordinate is a special kind of point because X comes before Y.
Sounds confusing?? Well let me help you firstly in a Co ordinate there is two numbers. There is also many types of lines for e.g
X is how far along
Y is how far up
M = Slope or Gradient (how steep the line is)
B = the Y Intercept (where the line crosses the Y axis)
Here is an Image of co ordinates:
