Define "Fracking" and ways it can alter/upset the water cycle.

Fracking can contaminate water supplies if it is not done properly, because the fracking fluid injected into rock to enable gas to be released often contains chemicals. If the borehole is not properly cased to stop leaks, the fracking water can escape into the aquifer

y = (3/2)x + 11

Step-by-step explanation:

We can start from the point slope form of a linear function:

(y-y1)=m(x-x1)

The slope m can be determined from the points given as m = (y2-y1)/(x2-x1)=(8-2)/(-2-(-6))=6/4=3/2

Then use either of the given points as x1, y1 to complete the equation (I picked the point (-6,2):

y-2=(3/2)(x+6)

You can rearrange this to:

y = (3/2)x + 11
