Question

Complete the following tables, if x and y are in direct proportion. ) 13 16 65 y - 55 - - 95​

Answer 1

The complete Table is:

• x __13 ____11 ____16 ____19
• y__ 65 ___ 55 ___80 ___ 95

Using the proportionality relation :

• y =kx ; k = constant of proportionality

Using the point (13, 65), we can find k ;

65 = 13k

k = 65/13

k = 5

The relationship is : y = 5x

For (_, 55)

55 = 5x

x = 11

For (16, _)

_ = 16(5)

y = 80

For (_, 95)

95 = 5x

x = 19
