Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet. In the rock cycle, there are three different types of rocks: sedimentary, igneous, and metamorphic. Sedimentary and igneous rocks began as something other than rock. Sedimentary rocks were originally sediments, which were compacted under high pressure. Hope this helps!

The slope is definitely negative, so you can cross out A and C. The slope of a line is always y/x. If you look at the point (-1,-1,) look up to point (-2,6.)
Comparing the two points I mentioned above, the y difference is 4 while the x difference is 1. This is also -4/1, meaning that the answer is B.
