Introduction
A linear equation in two variables represents a straight line.
General form: ax + by + c = 0.
General Form of Linear Equation
General form: ax + by = c
a and b are coefficients; c is constant.
Solution of a Linear Equation
A solution is an (x, y) pair that satisfies the equation.
Graphical Representation
Plotting (x, y) points gives a straight line.
Finding Intercepts
x-intercept: y=0
y-intercept: x=0
Applications of Linear Equations
Used in budgeting, speed-distance calculations, and more.
Conclusion
Linear equations have infinite solutions and form straight lines.
