If y varies directly as x, and y=6 as x=-1, find y for the x-value of 5

Step-by-step explanation:

we are given

y varies directly as x

so, we can write equation as

where

k is constant of proportionality

We have

at x=-1 , y=6

so, we can use it to find k

so, we get

now, we can plug it back

now, we can plug x=5

and we get
