If you could illustrate it with a graph to explain it more that would be great.

Suppose you buy a 7 percent coupon, 20-year bond today when it is first issued. If interest rates suddenly rise to 15 percent, what happens to the value of your bond? Why? Illustrate your explanations with a graph. If the market interest rate becomes higher than the interest rate of bond the value of bond shall decrease. Hence the price of bond shall fall.
