  Sketching Half-Planes

  A half-plane comes from an inequation. We still sketch a linear graph very similarly for half-planes, but from there ,we determine which region we need to shade...

  Working With Parallel And Perpendicular Lines

  When two linear graphs are parallel, they have the same gradient. When two linear graphs are perpendicular (at 90 degrees), if we multiply the two gradients, the result is -1.…

  Application of the Length of A Segment

  To find the length of a segment, we use Pythagoras' Theorem. However sometimes, we are given the length of a segment and the co-ordinates of one end. We are then expected to…

  Sketching Linear Equations - ax + by = c

  If we don't have gradient or y-intercept, we can sketch a graph by determining x- and y-intercepts which are done by letting y or x equal zero respectively and then solving for the other variable...
