in short, we simply split the total amount by the given ratio, so we'll split or divide 1020 by (15 + 2) and then distribute accordingly.

Regression line is given in the form of: y = a + bx
Where b is the gradient
Working out 'b'


Σxy - [ΣxΣy]/N

Σx² - [Σx]²/N



Working out 'a'
a = [∑y/N] - b[∑x/N]
a = [2650/460] - 0.264[3920/460]
a = 5.86 - 2.25
a = 3.61
Regression line equation is
y = 3.61 + 0.264x
