Hello everybody! I would really appreciate it if Somebody could give me the answer for this question and give a brief explanation on how they got it. Look at the photo for instructions!

Answer 1

Recall that the constant of variation of a straight line is the slope of the line.

To compute the slope we will use the following formula for the slope of a line:

`s=(y_2-y_1)/(x_2-x_1)\text{.}`

Now, notice that points (-1,3) and (1,-3) are on the line, then substituting these points in the above formula we get:

`s=(3-(-3))/(-1-1)=(6)/(-2)=-3.`

Answer: -3.
