12.02 Positive coordinates
Lesson
Are you ready?
Number lines help us work out distance and direction, and can be horizontal or vertical (think of a thermometer). Remembering how to plot points on a number line, will help us in this lesson.
Plot the following numbers on the number lines:
Plot $3$3 on the number line below.
Plot $528$528 on the number line below.
Plot $700$700 on the number line below.

Another phrase that we can use to describe a number plane is a 'coordinate plane'. This is because we locate coordinates on the plane.

Remember!
- axes - the horizontal and vertical lines, the $x$x-axis and $y$y-axis
- quadrants - the four different sections our axes create
- coordinates - these tell us where points are located, with an $x$x-value and a $y$y-value
- origin - where both $x$x and $y$y are equal to $0$0 and it's where both axes meet
