NettetLinear Function. A linear function is a function whose graph is a line. Linear functions can be written in the slope-intercept form of a line. f(x) = mx + b. where b is the initial or starting value of the function (when input, x = 0 ), and m is the constant rate of change, or slope of the function. The y -intercept is at (0, b). NettetStrategy for Solving Linear Equation in One Variable • Eliminate parentheses using the distributive property, and then combine any like terms. • Use the addition or the subtraction property of equality to write the equation with all variable terms on one side, and all constants on the other side. Simplify each side.
