2.) suppose y varies directly with x, and y= 10 when x= -3. what direct variation equation relates x and y? what is the value of y when x_ -1?

a. y= -3/10 x; 3/10

b. y= 1/10 x; -3/10

c. y= 10/3 x; -10/3

d. y= -10/3 x; 10/3

3.) suppose y varies directly with x, and y=8 when x= -6. what direct variation equation relates x and y? what is the value of y when x= -2?

a. y= -0.75x; 1.50

b. y= -1.33x; 2.67

c. y= 1.33x; -2.67

d. y= 0.13x; -0.25

4.) the equation of the line on the graph below is a direct variation equation. what is the constant of variation?
(it won't let me attach a graph so if you know what the graph is then in advance)

a. 1/4

b. 1/2

c. 3/4

d. 1

5.) for the data in the table, does y vary directly with x? if it does, choose an equation for the direct variation.

x y
8 11
16 22
24 33

a. yes; y = 2.75x

b. yes; y= 0.6875x

c. yes; y = 1.375x

d. no; y does not vary directly with x

    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

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

yes   because as the functions are graphed they eventually will intersect unless otherwise
