Answer:

its linear (i know how to draw the graph but i cant show you here, just make umm an x axis and y axis from 1 to 30 ) (also i feel like theres another way to know if its linear but this is how i would do it!)

Explanation:

to see if its linear ummm we first have to find the slope, the equation for the slope is

y2 - y1 / x2 - x1

lets use the points (2, 8) and (3, 12)

12 - 8/ 3 -2

4 / 1

4

y = 4x + b

now to find the y-intercept lets input a point we did not use yet

(5, 20)

20 = 4(5) + b

20 = 20 + b

b = 0

y = 4x

now we check if its linear with the points (6, 24) and (3.5, 14) sooo

24 = 4(6) ?

24 = 24

14 = 4(3.5) ?

14 = 14

so yes it is a linear graph

Yes because as x increases y increases in a constant manner.
If I were to make a quick guess I think this is the line y=4X
