Mathematics for IGCSE & O level - Coordinate Geometry (Section 2 - No. 45)
For a line segment with end points (0, 0) and (4, -3), what is the correct?
The gradient is -3/4.
The length is 5 units.
The midpoint is (2, -1.5).
The y-intercept is -3.

Gradient: (-3-0)/(4-0) = -3/4. Length: √(4^2 + (-3)^2) = 5, midpoint: (2,-1.5), y-intercept = 0.
