Answer:
D) No; y does not vary directly with x.
Step-by-step explanation:
We can affirm that y varies directly with x, that is, that y is directly proportional to x if they fulfill the following condition.
y/x = k
where,
k is a constant number
We have 3 ordered pairs:
a) (16, 4)
b) (32, 16)
c) (48, 36)
If we perform y/x for each ordered pair,
a) 4/16 = 0.25
b) 16/32 = 0.50
c) 36/48 = 0.75
Since y/x is not constant, y does not vary directly with x.
b. y=5/3x+2
c. y=-5/3x-2
d. y=5/3x-2
