Y 6 8 10 12 X - because it increases at a constant rate of 2
Chance coins have a greater mass because the coin mass of a quarter is 5.67 you multiply by 8, which is the number of quaters you have and you get 45.36 grams. if you do the same with the dollar coins, meaning you multiply the the mass by the number of coins, you should get 40.5 grams.
Sure your smart Its just not your subject....School isn't my thing but you put me out into the woods and i could survive weeks with nothing...Lol just find your nitch and be proud of it
Answer: y=-4x+13
Explanation : because it is :)
the easiest way I find a midpoint of two points is the midpoint theorem, here it is:

For x and y plug in the two coordinates given, (4,-4) & (0,8)
so once you plug the numbers into the equation you would get:
(2,2)
