Answer 2

let the cost of toy = X rs

and

cost of book = y rs

ATQ..

1 toy = 4(books)

X = 4(y)......‘eq1’

...

...

let y = 2..

by putting this value in eq 1 .. we get

X = 4 × 2= 8

let y = 1

there fore X = 4 × 1 = 4

let y = 0

X = 4 × 0 = 0...

...

we now just have to plot these value on a graph paper

(8‚3).. (4‚1)...(0‚0)..

....

.
