Mrs Omar runs the school tennis club. She has a bin of tennis balls and rackets for every 5 tennis balls in the bin there are 5 tennis rackets .draw a model to show the ratio of tennis balls to tennis rackets

x=y

Step-by-step explanation:

let x be the number of tennis balls and y the number of rackets.

-We divide the number of balls by the number of rackets to find out their ratio of proportionality:

-Hence, for each one ball there is one racket, so;

-This relationship is linear in nature, a direct variation, and can be graphed as attached below:

y = x + 95

y = 42 + 95

y=137 mm hg
