Q9 Help Plz

It's little tricky. You have to split the constant:

x^2 + 4x - 8
x^2 + 4x + 4 - 12
(x^2 + 4x + 4) -12

Now factorize the part in the brackets:

(x+2)(x+2) - 12

This can also be written as:

(x+2)^2 - 12

So, p = 2
and q = -12

The correlation is neg coz when u draw d line of best fit, it slopes downwards, gradient is also -ve. k?
Line of best fit is the STRAIGHT line drawn which has most of d points on d line or very close to it.
4 d English mrks, i think u will have to draw a line from 45 at d x-axis: Maths marks. Wherever it meets d line, take dis pt and join it 2 d y-axis. read d value on y-axis where dis line touches it. Hope u got it.
all d best
