Question

Ravish tells his daughter Aayushi 7 years ago I was 7 times as old as you will be if the present ages of Aarushi and Ravish Are X and Y respectively represent the solution algebraically as well as graphically

Answer 1

Let the age of Ravish be x and that of Aayushy be y.

So by condition 1st;

x-7=7(y-7)

x-7=7y-49

x-7y+42=0....(1)

For graphical representation

let x be 0

the x,y = by solving the equation 1 u will get :

(x,y) = (0,60

let y be 0 the x,y =by solving the equation 1 u will get :

(x,y) = (-42,0)
