When an object is divided into a number of equal parts then each part is called a fraction. A proper fraction has numerator and denominator mutually prime.

The amount of cake maria has is 8X. X is some positive real number.

She eats 3 slices, then the amount of cake left with Maria is 8X-3X=5X.

The fraction of cake left with Maria is \frac{5X}{8X}= \frac{5}{8}.

Is this linear relationship a direct variation?
Talja [164]

Since the ratio of of second variable to the ratio of first variable remains constant i.e y/x =8 so, the linear relationship is direct variation.

Step-by-step explanation:

A relationship is said to have direct variation if ratio of second variable to the ratio of first variable remains constant.

A relationship is direct variation if y=kx\,\,or\,\, \frac{y}{x} =k where k is the constant.

Now checking if the given data is having direct variation or not.

x       y

3       24

4       32

5       40

6       48

Now finding y/x

if y=24 and x = 3 then y/x = 24/3 = 8

if y=32 and x = 4 then y/x =32/4=8

if y=40 and x = 5 then y/x =40/5 =8

if y=48 and x = 6 then y/x =48/6= 8

Since the ratio of of second variable to the ratio of first variable remains constant i.e y/x =8 so, the linear relationship is direct variation.
