WebA linear equation is an equation for a straight line. These are all linear equations: y = 2x + 1 : 5x = 6 + 3y : y/2 = 3 − x: Let us look more closely at one example: Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line . When x increases, y increases twice as fast, so we need 2x;
WebAnswer (1 of 11): All lines are ‘straight’. When you say ‘equation’, you mean some coordinate system. Any line is going to intersect your coordinate system (let’s say you use the conventional x-y system) in 1 or 2 points.
