Lesson details
Key learning points
- Shapes on coordinate grids do not often have their measurements clearly written.
- Instead, you are expect to calculate the desired lengths.
- This may involve Pythagoras' theorem, shape properties or equations of lines for example.
Keywords
Equation of a straight line - An equation of a line is any equation whose graph forms a straight line. These equations can be written in the form y = mx + c.
Common misconception
"The graphs of two straight line equations should always intersect at integer points on a coordinate grid."
The location with which the graphs of two straight line equations intersect can be found by simultaneously solving the pair of equations. The graphs of two straight line equations can intersect at either integer or non-integer values.
