What to Focus On

  • Origin has coordinates (0,0)
  • Points on x-axis have y-coordinate = 0, form: (a,0)
  • Points on y-axis have x-coordinate = 0, form: (0,b)

  • Distance formula: d = √[(x₂-x₁)² + (y₂-y₁)²]
  • Distance is always positive (use absolute values)
  • Order of points doesn't matter: d(P,Q) = d(Q,P)

  • Section formula applies to internal division only
  • For ratio m:n, point P is closer to A if m < n
  • Mid-point divides segment in ratio 1:1

Common Mistakes to Avoid

The distance formula gives a negative answer when the second point has smaller coordinates than the first point

In coordinates (x,y), x represents horizontal distance and y represents vertical distance from origin

The section formula can only be used when m and n are positive integers

Memory Tips

Coordinate system with x-axis (horizontal) and y-axis (vertical)

Four quadrants and their sign patterns

Distance formula: sqrt[(x2-x1)² + (y2-y1)²]

Section formula for internal division: [(mx2+nx1)/(m+n), (my2+ny1)/(m+n)]
