Topics

  • Slope of a Line Or Gradient of a Line.
  • Parallelism of Line
  • Perpendicularity of Line in Term of Slope
  • Collinearity of Points
  • Slope of a line when coordinates of any two points on the line are given
  • Conditions for parallelism and perpendicularity of lines in terms of their slopes
  • Angle between two lines
  • Collinearity of three points
CISCE: Class 10

Definition: Slope

The slope m of a line is m = tan⁡θ

where θ is the inclination of the line with the positive x-axis.

CISCE: Class 10

Formula: Slope Between Two Points

\[m=\frac{y_2-y_1}{x_2-x_1}\]

CISCE: Class 10

Key Points: Concept of Slope

Nature of Slope

  • m > 0 → rising line

  • m < 0 → falling line

  • m = 0 → horizontal line

  • m = ∞→ vertical line

Parallel Lines 

Two lines are parallel ⇔ , their slopes are equal, m1 = m2

Perpendicular Lines

Two lines are perpendicular ⇔

Collinearity of Three Points

Points A, B, and C are collinear

Method 1: Distance method

AB + BC = AC

Method 2: Slope method

Slope of AB = Slope of BC
