Step-by-step explanation:
Equation :- 4x+3y=12
When the graph cuts x-axis, y coordinate becomes zero.
⇒4x+3(0)=12
⇒4x=12
⇒x=3
Similarly, when the graph cuts the y-axis, x coordinate is zero.
⇒4(0)+3y=12
⇒3y=12
⇒y=4
If OA=3units
OB=4units
By Pythagoras theorem
(AB)

=(OA)

+(OB)

=9+16
=25
=
25
⇒AB=5units
