Use the polygon formula (n-2) × 180 where n is the number of points
The polygon has 7 points
(7-2) * 180 = 5 * 180 = 900
All the angles should add up to 900
We need to use two points on the line: (0,50) and (2,100).
Then, we find the slope with the formula
Then, we use the point-slope formula to find the equation
Therefore, the right answer is B.
