A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation. STEP 1 - Draw ...

In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed ... Whole numbers make the working easier. Draw a triangle showing ...

Put simply, it’s the physics that explains how everything works: the best description we have of the nature of the particles that make up matter and the forces with which they interact.
