Question

The line 4x-3y-12 = 0 cuts the cordinates axis at A and B. Find the area od triangle OAB.

Answer 1

Answer:

put x=0 in the above equation

-3y-12=0, y=-4

now put y=0

4x-12=0, x=3

Area=(1/2)×3×4=6 Ans

when the line cuts x axis, it's y value is 0

similarly when the line cuts y axis, it's x value is 0
