Add up each of the numbers (32) and then divide by the amount of numbers (8) :)
If you mean points of: (0, 1) and (4, 4) Then the slope is: 3/4
1. Find the arithmetic mean (average)2. Find the distance of each number from the mean (x-the mean=?)3. Square each number4. Add up all of the squares5. Divide the final sum by the original meanEX: Set: 1, 3, 4, 5, 71. 1 + 3 + 4 + 5 + 7 = 20 / 5 = 42. 1-4=-3 3-4=-1 4-4=0 5-4=17-4=33. 3*3=9 1*1=1 0*0=0 1*1=13*3=94. 9 + 1 + 0 + 1 + 9 = 205. 20 / 4 = 5
If you mean points of: (0, 1) and (4, 4) Then the slope is: 3/4

I was only able to get 13 but I think there can be more, this is what i got: 0+0+4=4 4+0+0=4 0+4+0=4 0+1+3=4 0+3+1=4 0+2+2=4 1+2+1=4 1+1+2=4 1+3+0=4 2+2+0=4 2+0+2=4 3+1+0=4 3+0+1=4

The arithmetic mean is 2.
If you mean points of: (5, 4) and (0, 3) then the slope is 1/5

Variance = sigma((value - mean)2) / (# values - 1) Mean = (0+1+1+2)/4 = 1 Variance = ((0-1)2+(1-1)2+(1-1)2+(2-1)2)/(4-1) Variance = (1+0+0+1)/3 Variance = 2/3 Variance ~ 0.667
