The answer is 6 degree.
Step by step process
The formula for calculating the measure of each exterior angle of a polygon is (360/n).
The number of sides of 56-gon(n) = 56.
So, each exterior angle 
 = (360/56)
 = 6.43 or 
 6(approximately)
        
             
        
        
        
Answer:

Answer:

Step-by-step explanation:
Hi there!
Slope-intercept form:  where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
 where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
<u>1) Determine the slope</u>
 where the two given points are
 where the two given points are  and
 and 
Plug in the given points (-1, 4) and (0, 2)

Therefore, the slope of the line is -2. Plug this into  :
:

<u>2) Determine the y-intercept</u>

Recall that the y-intercept is the value of y when the line crosses the y-axis, meaning that the y-intercept occurs when x is equal to 0.
One of the given points is (0,2). Notice how y=2 when x=0. Therefore, the y-intercept of the line is 2.
Plug this back into the equation:

I hope this helps!
