Understanding Linear Equations
A linear equation in two variables (typically x and y) is an equation that can be written in the form ax + by = c, where a, b, and c are constants, and a and b are not both zero. The graph of a linear equation is always a straight line.
Key Concepts:
- Coefficients (a, b): These numbers determine the slope and direction of the line.
- Constant (c): This value affects the position of the line on the coordinate plane.
- Slope: The slope of the line (if b ≠ 0) is -a/b, indicating its steepness and direction.
- Intercepts:
- x-intercept: The point where the line crosses the x-axis (set y=0 and solve for x).
- y-intercept: The point where the line crosses the y-axis (set x=0 and solve for y).
This tool helps you visualize how changing the coefficients and the constant term affects the graph of a linear equation. Experiment with different values to deepen your understanding of linear relationships!
