Answer:
The sum of interior angles is found by using the following equation:
∑ of interior angles = (S - 2)180
S = sides.
Note that the sum is given to you, or 1620. Plug in 1620 for the sum:
1620 = (S - 2)180
Next, isolate the variable, s. Note the equal sign, what you do to one side, you do to the other. Divide 180 from both sides:
(1620)/180 = ((S - 2)180)/180
S - 2 = 1620/180
S - 2 = 9
Next, isolate the variable, s. Add 2 to both sides:
S - 2 (+2) = 9 (+2)
S = 9 + 2
S = 11

Answer:4,1x101, 9, 4.1, 2, 0.42, 0.042
Step-by-step explanation:
To determine the slope of the line, identify two points that lie on it. Let x be zero and solving for y gives y = 5. Hence, the point (0, 5) lies on the line. Furthermore, by letting y be zero and solving for x gives x = 5. Thus, the point (5, 0) is also on the line. Use the formula for slope which is,
m = (y2 - y1) / (x2 - x1)
m = (0 - 5) / (5 - 0) = -1
Therefore, the slope of the line is -1.
