EASY PERIOD
The standard form:

The slope-intercept form:

m - slope

b - y-intercept (0, b).
We have the point (0, 43) → b= 43.
Next point (2, 55). Substitute to the slope formula:

Therefore we have:
<em>subtract 6x from both sides</em>

Step-by-step explanation:
hope you can send the questions again because your question is to long to answer everything. I answered 1,2,3,4
The answer should be n=-8
The y-intercept is 1/3 or (0, 1/3)
hope this helped !!
