<h3>Given ↓</h3>
- Two points that a line goes through
<h3>To Find ↓</h3>
<h3>Calculations ↓</h3>
When we have two points that a line passes through and asked to determine the slope of the line, the slope formula is going to come in handy.
This is the formula :

y2 and y1 are y-coordinates, and x2 and x1 are x coordinates
Plug in the values :


Which simplifies to
, or 1

Answer:
<h2>
0.05543</h2>
Step-by-step explanation:
The formula for calculating the margin of error is expressed as;
where;
z is the z-score at 95% confidence = 1.96 (This is gotten from z-table)
p is the percentage probability of those that watched network news
p = 40% = 0.4
n is the sample size = 300
Substituting this values into the formula will give;

Hence, the margin of error for this survey if we want 95% confidence in our estimate of the percent of T.V. viewers who watch network news programs is approximately 0.05543
