When a line is given in the form

The slope of the line is m. So, in this case, the slope of
is 1.
Given a slope
, you find the slope of a perpendicular line
by imposing

So, if the given line has slope 1, a perpendicular line has slope
given by

and thus 
So, we want a line with slope -1 and passing through (12,-1). Using the fomula

we get

Answer: Minerals can form from volcanic gases, sediment formation, and crystallization from magma.
Step-by-step explanation: hope this helps

Step-by-step explanation:
We start by applying the Pythagorean theorem to the ladder, with its length L as the hypotenuse:

where x is the vertical distance from the top of the ladder to the ground and y is the horizontal distance from the bottom of the ladder to the wall. Taking the derivative of the above expression with respect to time, we get

Solving for dx/dt, we get

We know that

when x = 6 ft. So the rate at which the top of the ladder is going down is


The negative sign means that the distance x is decreasing as y is increasing.
Answer:

Step-by-step explanation:

It will be x=1/a because it that hard to solve
