Answer:
n=2
Step-by-step explanation:
4(5n-7)=10+2
1) First, distribute (multiply out 4)
20n-28=10+2
2) Combine like terms (add 10 and 2)
20n-28=12
3) Isolate the variable (Add 28 to 12)
20n=40
4) Isolate the variable (Divide by 20)
n=2

I'm assuming there is probably a graph that goes with this problem so here is all the info I can give you with the four choices:
If it is -1/3, the line will go DOWN 1, over 3 (just count on the graph)
If it is 3, the line will go UP 3, over 1
If it is 1/3, the line will go UP 1, over 3
And if it it -3, it will go DOWN 3, over 1
(If the slope is 3 or -3, it would be quite steep compared to a slope of 1/3 or -1/3)
Hope that helps!
