Answer:
The slope of the line is -1/2
Explanation:
The general equation of a line is

where
m is the slope of the line, which is the rate of change of the y-variable with respect to the x-variable
q is the y-intercept, which is the y-coordinate at which the line touches the y-axis
The equation of the line given in this problem is

Therefore, by comparing it with the general equation, we observe that:

Therefore, the slope of this line is -1/2.

Answer: c. occur gradually over millions of years.
Explanation:
Lithospheric plates exist under the surface of the earth that we see and form part of the earth's crust. They rest on the mantle which is very hot and as a result of this temperature, these plates are always moving.
These movements however occur gradually over millions of years which is why we do not notice it happening but these plate movements are very influential as they lead to the production of various land masses such as mountains when the movements lead to the plates colliding.
