Answer:
-1 :)
Step-by-step explanation:
(3,4)(2,-1)
slope(m) = (y2 - y1) / (x2 - x1)
slope(m) = (-1-4) / (2 - 3) = -5/-1 = 5
y = mx + b
slope(m) = 5
u can use either of ur points...(3,4)...x = 3 and y = 4
now we sub and find b, the y int
4 = 5(3) + b
4 = 15 + b
4 - 15 = b
- 11 = b
so ur equation is : y = 5x - 11 <===
Polygons are closed figures so any figure that is not closed is not a polygon
