Question -
Answer -
The co-ordinates of mid-point of the line segment joining thepoints P (0, – 4) and B (8, 0) are (0+8)/2, (-4+0)/2 = (4, -2)
The slope ‘m’ of the line non-vertical line passing through thepoint (x1, y1) and
(x2, y2) is given by m = (y2 – y1)/(x2 – x1) where, x ≠ x1
The slope of the line passing through (0, 0) and (4, -2) is(-2-0)/(4-0) = -1/2
∴ Therequired slope is -1/2.
