Recall that if two straight lines are not parallel, they meet at a point when produced. Observe lines l and m which meet at a point (O). In the diagram, l and m are called intersecting lines. O is called the point of intersection. Similarly two line segments or two rays may intersect at a..

The position of a point in a plane is determined by two coordinates. The method is as follows: Two mutually perpendicular lines (straight lines) XX' and YY' are drawn as shown in the figure. These straight lines are termed as coordinate axes, the one (usually drawn horizontally) is called the x-axi..

This Tutor Vista is GREAT! loved this session, it helped me heaps.
i loved the session... she was a great tutor.. she helped me alot and now i have a good understanding of fractions.. thank you! :)
You are an amazing tutor. So knowlegeable and patient. Very clear in explanations, 2 thumbs up -kelly
this is lawrens mom and I really like the way they work the entire problem out and show all the work. its exactly what she needs
Looking for More Help!
