If the gradient of the line through point A(-1, n) and S(-4, -2n) is 2, then the value of n is ...

Question

Just ask, I am from Indonesia :)

Answer 1

"gradiant" be the slope=tangent=dy/dx

Hav no idea wot A or S mite be...perhaps 2 points on a kerv???????

me sorta ges yu sae slope=2, but yu hide it good in mung lotta nois

slope=deltay/deltax

me assume point1=(-4,2n) & point2=(-1,n)

deltax=from -4 tu -1...3

deltay=n-(2n)=-n

slope=2=deltay/deltax=-n/3

n=-3*2=-6

Answer 2

n=-10
