We still sketch a linear graph very similarly for half-planes, but from there ,we determine which region we need to shade...mrmarcok (25)in math • 6 years agoWorking With Parallel And Perpendicular LinesWhen 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. These facts allow us…mrmarcok (25)in math • 6 years agoApplication of the Length of A SegmentTo 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 determine the…mrmarcok (25)in math • 6 years agoMidpoint of A SegmentIf we are given a segment, which is a piece of a linear graph, sometimes we may want to determine its midpoint...mrmarcok (25)in math • 6 years agoDetermining A Linear Equation From Its GraphIf we are given a linear graph, we can determine the equation to make that graph. This is handy to make conclusions about data...mrmarcok (25)in math • 6 years agoSketching Linear Equations - ax + by = cIf 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...mrmarcok (25)in math • 6 years agoSketching Linear Equations - y = mx + cWhen given the gradient and y-intercept, use these to sketch the linear graph...mrmarcok (25)in math • 6 years agoSolving linear inequationsWe solve linear inequations the same was as we solve linear equations.
