x y k
0.5_________8
1___________8
2___________8
3___________8

Answer 1

Answer:

y=4,y=8, y=16, y=24

Step-by-step explanation:

Assume that the variables x and y are directly related. If k = 8, what is the value for each of the following points? Be sure and record your data to be used in the following problem.

x y k

0.5_________8

1___________8

2___________8

3___________8

y is directly proportional to x

y$\alpha$x

therefore y=kx.........

k=y/x

k=8

equation 1 can also be written as

y=8x

x=o.5

y=8*0.5

y=4

when x=1

y=8*1

y=8

when x=2

y=2*8=16

when x=3

y=8*3

y=24

Answer 2

The equation for this function is:
y = kx
y = 8x

For each value of x;

(0.5 , 4)
(1 , 8)
(2 , 16)
(3 , 24)
