Question

the cost of a note book is twice the cost of a pen .write a linear equation in two variables to represent the statement.also draw the graph of the same​

Answer 1

Answer:

X-2y=0

Step-by-step explanation:

Let the cost of a notebook be 'x' and the cost of a pen be ₹y

According to question

x=2y

or

x-2y=0

Answer 2

let X be cost of note book and Y be cost of pen

so X=2Y

so equation is x-2y=0

for plotting the graph,take any value of Y

if y=1,x=2*1=2

if y=2,x=4

if y=5,x=10

now plot the graph of co-ordinates (1,2),(2,4),(5,10)

you can take any value for Y instead of value taken by me
