Answer 1

First we have to figure out what we need to multiply 6 by to get 15, then we multiply that same number by x to get out solution
To figure out this number, we divide 15 by 6, which comes out to 2.5.

See if you can finish this, let me know if you get stuck.

Answer 2

what do i have to do after that

Answer 3

Multiply 2.5 by the value of x (which is -2)

Answer 4

y varies directly with x implies:

\(\Large \frac{x_1}{y_1} = \frac{x_2}{y_2} \)

\(\Large \frac{-2}{6} = \frac{x_2}{15} \)

\(\Large x_2 = \frac{-2}{6} * 15 = \frac{-30}{6} = -5 \)
