NettetA linear equation is an equation of a straight line, written in one variable. The only power of the variable is 1. Linear equations in one variable may take the form a x + b = 0 a x … NettetWithout knowing x and y, we can still work out that ( x + y) 2 = x 2 + 2 x y + y 2. “Linear Algebra” means, roughly, “line-like relationships”. Let’s clarify a bit. Straight lines are predictable.
