(i) the coordinates of A and of B,

(ii) the length of the line segment AB,

(iii) the coordinates of the point C that lies on the line I such that C is equidistant from the coordinate axes,

(iv) the equation of the line OC, where 0 is the origin.​

Answer:

As the point A lies on the x - axis, its y coordinate =0.

To find the co-ordinates of the point A, substitute y=0 in the equation of the line 3x−4y+12=0.

Hence, 3x−4(0)+12=0.

=>3x=−12

=>x=−4

So, point A =(−4,0)

Similarly, as the point B lies on the y - axis, its x coordinate =0.

To find the co-ordinates of the point B, substitute x=0 in the equation of the line 3x−4y+12=0.

Hence, 3(0)−4y+12=0.

=>4y=12

=>y=3

So, point B =(0,3)
