Answer:

Step-by-step explanation:

Inverse variation is of the form

xy = k where k is a constant

x=4 and y = 32

4*32 = k

128 = k

xy = 128

Let x = 8

8y = 128

Divide each side by 8

8y/8 = 128/8

y =16

Find the slope of the line that passes through the points (2,1) and (-7,4)

VladimirAG [237]

Answer:

$-\frac13$

Step-by-step explanation:

Just the slope, so we can simply apply the definition, as variation in y over the variation in x

$m= \frac{\Delta y}{\Delta x} = \frac{1-4}{2-(-7)} = \frac {-3}{9} = -\frac13$
