i'm confusing myself. anyone else gettin 2.6 for the gradient? :S
the way im taught how to do these is: to find the gradient y2-y1/x2-x1 = -4 - 9 / -11 + 6
= -13/-5
= 2.6
then use the equation y-b=m(x-a) and put in the values (-6,9) = (a,b) and (-11, -4) = (x, y)
so it'll be -4 - 9 = 2.6(-11 -(-6))
but i think i've done it wrong =/ sorry. cause we normally use the equation to find out the 2 points you don't know :S.
