The line graph
First, consider the following points on the graph.


First, calculate the slope.



undefined
Since, the slope is undefined; we simply consider only the value of x.
The line equation is:

Step-by-step explanation:
Answer:
Marty's function has larger slope as compared to Ethan's slope.
Step-by-step explanation:
Marty function:
y plus 3 equals StartFraction 1 Over 3 EndFraction left-parenthesis x plus 9 right-parenthesis.
Writing in mathematical form: 
Marty has written expression in point-slope form:
where m is slope
So, comparing Marty's equation with general point-slope form equation we get slope 
Now, Ethan has a table
x y
-4 9.2
-2 9.6
0 10
2 10.4
We can find slope using formula: 
Using any two points, we can find slope of Ethan's equation

So, we get Marty's slope = 0.3
Ethan's slope = 0.2
So, Marty's function has larger slope as 0.3 is greater than 0.2
Well what are the numbers they give you
