If a straight line passing through the point is such that its intercepted portion between the coordinates axes is bisected at P, then its equation is :
The distance on the x-axis from the origin where the straight line cuts it.
Intercept form of a straight line -
and are the -intercept and -intercept respectively.
So that line say intersect y-axis at (o,b ) and x-axis at (a,o).
since it is bisected at p (-3,4)
