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

y is directly proportional to x
y 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
The equation for this function is: y = kx y = 8x For each value of x; (0.5 , 4) (1 , 8) (2 , 16) (3 , 24)
