The value of proportionality constant is: 1.88
Step-by-step explanation:
Direct variation means that increase/decrease in one quantity also causes increase/decrease in other quantity.
Given that
y varies directly with x
It means
y∝x
Can also be written as:
[tex]y = kx[/tex]
Putting the given values of x and y
[tex]y = kx\\15 =8k\\k =\frac{15}{8}\\k = 1.875[/tex]
So, after rounding k = 1.875, we get
[tex]k = 1.88[/tex]
Hence, the value of proportionality constant is: 1.88
