Can I please get some help with this!!!!!!!!!!! Just 3 problems

Question

Consider the following "table" of functional values: (-1,-1.32), (-0.2,-6.6), (1.1,1.2), (2.2,0.6). Does the function vary directly, vary inversely, or neither? If it varies, what is the constant of variation?
 

Varies directly; k = 1.32

Neither, since xy is not a constant

Neither, since y/x is not a constant

Varies inversely; k = 13.2

Varies inversely; k = 1.32
 

Consider the following "table" of functional values: (-1.5,-6), (1,4), (2.1,8.4), (3.6,14.4). Does the function vary directly, vary inversely, or neither? If it varies, what is the constant of variation?
 

Varies inversely: k = 4

Varies directly: k = 1/4

Varies inversely: k = 1/4

Neither

Varies directly: k = 4
 

The variables x and y vary inversely. Write the function that models this inverse variation if x = 7 when y = 42.
 

y = 6 / x

y = 294 / x

y = 6x

x = 294y

y = 294x

Answer 1

1st problem answer: Neither. just graphically plot the points. no relation, not direct or inverse

2nd problem, plot the points y=2.1x, k = 2.1, direct variation

as x goes up, you goes up

3rd: x=7, y=42 varying inversely. y = k/x 42(7)= k = 294

y = 294/x

as x goes up, y does down, an inverse relationship
