ANSWER
The standard form is:

EXPLANATION
The given line passes through (4,10)and (6,11).
The slope of this line is


The equation is given by the formula,

We plug in the first point and the slope to get.




The standard form is

When a graph is flat, all of the y values for the domain are equal, so the graph has a slope of zero.
I think the answer is no solution
5n+ 5= 17
5n= 17-5
5n= 12
N= 12/5
N= 2.4
The answer is 2.4.
Hope this helps!
