General form of a linear regression equation :
y = b1x + b0
b1 = slope ; b0 = intercept
Using an online regression calculator, the regression equation obtained is :
y = 5.8286 + 52.2286x
Comparing the equation ;
b1 = 52.23
b0 = 5.83
Ответ:
x=(-b+/√b²-4ac)/2a
D=b²-4ac=25+4*6*4=121, √D=√121=11
x=(5+/-11)/12
x1=-6/12=-1/2
x2=16/12=4/3
