Q5 of 112 Page 156

Find the slope of the line which passes through the origin and the midpoint of the line segment joining the points (0, – 4) and (8, 0).

We need to find slope of a line passing through origin (0, 0) & mid–point of P (0, –4) and Q (8, 0)


Let M mid–point of P (0, –4) and Q (8, 0)


Mid–point formula M (x, y)


Mid–point of PQ




We know that,


Slope of line passing through (x1, y1) and (x2, y2) is



Slope of line between points O (0, 0) and M (4, –2)




Hence, slope of line is
