Please help with this question

Answer:
The answer is y=1.4x
Step-by-step explanation:
You have to find the change of y over the change of x. So you have to find how much each value is changing by.
Y-side
5.6-2.8= 2.8
8.4-5.6=2.8
11.2-8.4=2.8
X-side
4-2=2
6-4=2
8-6=2
If you divide 2.8 by 2 you get 1.4
So the slope is 1.4
