If y varies directly as x, and y=6 as x=-1, find y for the x-value of 5
Tema [17]

Answer:

y=-30

Step-by-step explanation:

we are given

y varies directly as x

so, we can write equation as

y=kx

where

k is constant of proportionality

We have

at x=-1 , y=6

so, we can use it to find k

6=k(-1)

so, we get

k=-6

now, we can plug it back

y=-6x

now, we can plug x=5

and we get

y=-6\times 5

y=-30
