Since the ratio of of second variable to the ratio of first variable remains constant i.e y/x =8 so, the linear relationship is direct variation.
Step-by-step explanation:
A relationship is said to have direct variation if ratio of second variable to the ratio of first variable remains constant.
A relationship is direct variation if where k is the constant.
Now checking if the given data is having direct variation or not.
x y
3 24
4 32
5 40
6 48
Now finding y/x
if y=24 and x = 3 then y/x = 24/3 = 8
if y=32 and x = 4 then y/x =32/4=8
if y=40 and x = 5 then y/x =40/5 =8
if y=48 and x = 6 then y/x =48/6= 8
Since the ratio of of second variable to the ratio of first variable remains constant i.e y/x =8 so, the linear relationship is direct variation.

The solution of the first graph is 1, 2 while the second graph is a straight line.
<h3>How to solve for the graph</h3>We have y > 2x
y< x
First you have to replace the inequality by a mathematical operator
y - 2x = 0
y - 3 = 0
equation 1 is of the form
y = mx
The slope here is 2,
to make a graph we need to have x = 1 then the line would pass through
(1,2).
The second equation is simply a second line that would pass through the x axis.
The correct graph is below:
