Straight Line Equations
In mathematics, straight line equations describe linear relationships and are crucial in geometry and algebra. They are represented in the form:
ax + by + c = 0
Here, a and b are coefficients, and c is a constant term.
Example:
Consider this straight line equation: 4x + 5y + 3 = 0
Standard Form:
y = mx + b
In this form, m represents the slope, indicating the gradient or steepness of the line:
Given two points with coordinates (X1, Y1) and (X2, Y2):
How to Solve Straight Line Equations:
- Step 1: Determine the slope m, also known as the rise over run.
- Step 2: Determine the y-intercept b.
- Step 3: Write the equation in standard form: y = mx + b.
