Answer:
y=x and y=1
4 x
Step-by-step explanation:
We know,
'Direct Variation function' is the function where two quantities vary directly i.e. variables x and y are said to be directly varying if 'y=kx' where k is the constant of variation.Thus, from the options, we see that the function,
y=x
is varying directly with the constant of variation i.e. k = 1.
y= 1
4 x
is also varying directly with constant k=1

Answer:

Step-by-step explanation:
a)
![[ \ where \ k \ is \ a \ constant \ ]](https://tex.z-dn.net/?f=%5B%20%5C%20where%20%5C%20k%20%5C%20is%20%5C%20a%20%5C%20constant%20%5C%20%5D)
<em><u>Find k.</u></em>
Given x = 12, y = 5,

b)
<em><u>Find x.</u></em>
Given y = 10
We have k = 300

c)
<u><em>Find y</em></u>
Given x = 3
We have k = 300
