However, should know how the method of least squares works..same result
but might be a need to know.
x	y	xy	x^2
32	15	480	1024
33	16	528	1089
35	18	630	1225
34	17	578	1156
36	16	576	1296
36	16	576	1296
39	19	741	1521
42	24	1008	1764
287	141	5117	10371
141 = 8a + 287b		
5117= 287a + 10371b
a= 1322362/74073 and b =-469/4073   	
y = a + bx
