Marks: +1, -0

The length of the intercept of the graph of the equation 9x - 12y = 108 between the two axes is:

Solution:

The given equation is 9x − 2y = 108.

\table x,-0x12;y,-9,0

9x - 2y = 108

Now by Pythagoras theorem,

(OA)^2+(OB)^2

(AB)^2

(-9)^2+(12)^2

AB^2

81+144 =

AB^2

√{225}

= AB
AB = 15 units
