Equations {linear equation} {first-degree equation} can have variables raised only to first power.
graph
Linear-equation graph is a straight line.
form
Standard form is a1 * x1 + a2 * x2 + ... + aN * xN = b, where b is constant, a1 to aN are coefficients, and x1 to xN are variables.
homogeneous
Linear homogeneous equations equal zero.
one variable
Linear equation can have only one variable: a1 * x1 = b. Straight line can have point where line intercepts y-axis {y-intercept} and point where line intercepts x-axis {x-intercept}. Straight line inclines to x-axis {slope, line}.
