Types

1. Parallel Lines
2. Perpendicular Lines
3. Intersecting Lines
4. Concurrent Lines

Slope

The ratio of vertical rise of any two points on a line to distance between them is called slope of a straight line and it can be evaluated in two different methods.

1. Slope in Trigonometric form
2. Slope in coordinates form

Equations

The straight lines are written mathematically in algebraic form.

1. Slope Intercept form
2. Intercept form
3. Point Slope form
4. Two Point form
5. Standard form
