Question

What is the constant of variation k of the line y=kx through (5,8)

Answer 1

`k=(8)/(5)`

Explanation:

find the constant of variation k of the line y=kx through (5,8)

Use equation of line
`y=kx`

k is the constant of variation

LEts find out k using the point (5,8)

x=5 and y=8, plug in the values

`8=k(5)`

To get k alone, divide by 5 on both sides

`k=(8)/(5)`

Answer 2

k= 8/5

Explanation:

here x= 5 and y= 8

we have y=kx

k= y/x

k= 8/5 this is constant of variation
