Q7. When x is a factor of 2 smaller, y is a factor of 2 larger. (That is what inverse variation means.) y = 2*3.
  C)   y = 6


_____
Another way to look at is that "inverse variation" means the product of x and y is a constant. Here, that constant is (3)·(-8) = -24. Then when x=-4, y=-24/-4 = 6.

Complete the equation of the line through [1,4] and [2,2]
son4ous [18]

First find the slope of the line so change in y over change in x so 4-2/1-2 which is 2/-1 so -2 is your slope then plug that as well as a point from above to find your y intercept so y=mx+b 2=-2(2)+ b then you have 2=-4+b then add 4 to each side and you find b is six then you make ur equation from your slope and y int(b) y=-2x+6
