If you look at the data, you can see that every y value is opposite to the corresponding x- value.
So, equation can be written as
y = [-] x or y=[-1]x
4½ = 9/2
1 2/5 = 7/5
9/2 * 7/5 = 63/10 = 6 3/10
125 percent you divide 10 by 8 and get 1.25 then moved the decimal point to the right two spots
Since 41 is greater than the sum of the other two sides this is not a triangle.
