In Coordinate Geometry, we use graphs and coordinates to find measurements of geometric figures.

Important Formulas
- Distance PQ =
- Slope of PQ = m =
- Equation of or y = mx + c
- The product of the slopes of two perpendicular lines is –1.
- The distance between the points (x1, y1) and (x2, y2) is
- If point P(x, y) divides the segment AB, where A ≡ (x1, y1) and B ≡ (x2, y2), internally in the ratio m: n, then,
x= (mx2 + nx1)/(m+n)
and
y= (my2 + ny1)/(m+n)
- If P is the midpoint then,
- If G (x, y) is the centroid of triangle ABC, A ≡ (x1, y1), B ≡ (x2, y2), C ≡ (x3, y3), then,
x = (x1 + x2 + x3)/3 and y = (y1 + y2 + y3)/3
- If I (x, y) is the in-centre of triangle ABC, A ≡ (x1, y1), B ≡ (x2, y2), C ≡ (x3, y3), then, where a, b and c are the lengths of the BC, AC and AB respectively.
- The equation of a straight line is y = mx + c, where m is the slope and c is the y-intercept (tan θ = m, where θ is the angle that the line makes with the positive X-axis).
