Find the average x.
x%5Bave%5D=%2812%2B14%2B10%2B9%2B15%2B8%29%2F6
x%5Bave%5D=11.333
Find the average y.
y%5Bave%5D=%2829%2B35%2B28%2B23%2B36%2B18%29%2F6
y%5Bave%5D=28.167
For a simple linear regression Y=a%2BbX, use the following formula to find the slope,

b=93.6667%2F39.333
b=2.381
a=y%5Bave%5D-bx%5Bave%5D
a=28.167-2.381%2811.333%29
a=1.178

Y=2.381X%2B1.178
