The sum of all exterior angles is always 360 degrees.
360/40=9 sides
the polygon has 9 sides.
y = mx + b
-3 = -2(-5) + b
-3 = 10 + b
-13 = b
y = -2m - 13
The line would pass through -13 on the y-axis and it would go down 2 and move to the right 1 for every new point.
Hope this helps! ;)
3 is the remainder because the closest is 7 times 21 so it’s remainder 3
"color the piece according to your color chart." Do you have that? If you don't, I wouldn't worry, you still did all the work and got all the answers, so your teacher should be fine with it.
