Linear Equations

A linear equation is an equation that makes a straight line when graphed. It can be written in the form ax + b = c, where a, b, and c are constants.

The slope of a line represents the rate of change of the y-coordinate with respect to the x-coordinate. It indicates how steep the line is.

The y-intercept is the point where the line crosses the y-axis. It is the value of y when x = 0.

To solve a linear equation, isolate the variable on one side of the equation using inverse operations.

a = 3.

The equation 2x = 10 has x = 5 as the solution.

n = -4.

y = 3x - 2.

z = 12.

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers.
