I believe that the perpendicular equation would be the opposite sign and the reciprocal of the original slope. Then you just plug in the x and y coordinate to y=mx+b and solve for b.
y=4x+b
3=4(-4)+b
3=-16+b
b=19
y=4x+19
Answer:
It is asking what type of environment was the rock formed in. For example, metamorphic rock and sedimentary rocks are formed at different levels of temperature and pressure. To solve the problem start off with trying to identify the type of rock (igneous,metamorphic, sedimentary,etc.) and then figure out what conditions those rocks form in. I hope this helps! Good luck!
