Answer:
2.) D
3.) B
4.) See attached graph
5.) C
Step-by-step explanation:
2.)
We are told that "y" varies directly with "x"
So the equation is of the form y = K*x
y= 10 when x= -3.
K = 10/-3
Correct answer = D
3.)
We are told that "y" varies directly with "x"
So the equation is of the form y = K*x
y=8 when x= -6.
K = 8/-6 = -4/3 = -1.3333
Correct answer = B
4)
We are told that the equation is a direct variation. In the attached picture I plotted all the possible options, since you didn't attach the corresponding image.
We can see that all graphs are direct variations winth different slopes (constant of variation)
A. K = 0.25
B. K = 0.5
C. K = 0.75
D. K = 1
5)
To find out if y varies directly with x, we divide several points and find the realtion between them
y = K*x
11/8 = K
22/16 = 11/8 = K
33/24 = 11/8 = K
K = 11/8 = 1.375
It is a direct variation
Correct answer = C
