Answer 1

`k = -3`

Explanation:

Step 1: Substitute

To solve this problem you are going to need to substitute the values of y and x into the problem y=kx. Which would give you the problem of 3=-1k or 3 = -k to make things easier.

Step 2: Using properties of equality

In order to isolate the value of k you would need to divide both sides by -1 because division cancels out multiplication. You would get
`(3)/(-1) = (-k)/(-1)` or
`-3 = k`

Step 3: Check

In order to check this problem you would need to insert the values back into the original equation and solve. So that would be 3= -1*-3 which does equal 3. So the answer is correct

Answer 2

`k = - 3`

Explanation:

`y = kx`

`k * ( - 1) = 3`

`- k = 3`

`k = - 3`
