The equation for this is (n-2) x 180
Replace n with the number of sides:
a. 9: (9-2) x 180 = 7 x 180 = 1,260
b. 19: (19-2) x 180 = 17 x 180 = 3,060
Answer:
Option B
Step-by-step explanation:
Option A, C and D have x- values that repeat and you cannot have that.
Y values can repeat but not x-values.
Option B has all x values with different y-values
Answer:

Step-by-step explanation:
The data is not collected from the world outside, but a computer.
=> The data can be generated under assumption from simulation only.
=> Option A is correct.
Hope this helps!

(y - yo) = m.(x - xo)
We have two points (-4, -1) and (1, 4)
(-1 - 4) = m.(-4 - 1)
(-5) = m.(-5)
m = (-5)/(-5)
m = 1
So the slope is 1
