Eric has only pennies in dimes in his coin collection he has five times as many pennies and dimes which is an expression for the number of coins in his collection using d for the number of dimes

Amount that Eric has got in dimes = d

Number of coins which is in  pennies = p

It is given that amount in dimes is five times the number of coins which is in penny.

So,the expression will become

 A.T.Q

⇒ Total dime = 5× Total number of coins which is in penny

⇒ d = 5 p

If you want solution of this equation , the graph will be a straight line which passes through the origin making an angle of with the positive direction of X-axis.

The solution of the linear expression lies in First quadrant.

For every positive integral value of p>0 , there are infinite number of solutions for number of dimes.For example take p =1,2,3,...

we get d=5,10, 15,....
