Soulotion to equation if y is =15 when x=2 ,find y when x=8

skelet666 [1.2K]

Answer:

The value of y for x = 8 is 60 .

Step-by-step explanation:

Given expression as :

For x = 2 , y = 15

Let the equation be written with constant k'

So, y = k x

Or, k = $\dfrac{y}{x}$

∴ k = $\dfrac{15}{2}$

<u>Now, again </u>

For x = 8

equation can be written as

y = k x

Or, y = $\dfrac{15}{2}$ × 8

Or, y = $\frac{15\times 8}{2}$

∴ y = 15 × 4

I.e y = 60

Hence The value of y for x = 8 is 60 . Answer
