Answer:

Step-by-step explanation:

Apply formula:
and

We get:







Hence final answer is

X(u, v) = (2(v - c) / (d - c) + 1)cos(pi * (u - a) / (2b - 2a))
y(u, v) = (2(v - c) / (d - c) + 1)sin(pi * (u - a) / (2b - 2a))
As
v ranges from c to d, 2(v - c) / (d - c) + 1 will range from 1 to 3,
which is the perfect range for the radius. As u ranges from a to b, pi *
(u - a) / (2b - 2a) will range from 0 to pi/2, which is the perfect
range for the angle. So, this maps the rectangle to R.

Answer:
slope = 4
Step-by-step explanation:
We can find the slope of a line when knowing 2 points by using the slope formula,
.
and
represent the x and y values of the first point, respectively.
and
represent the x and y values of the second point, respectively.
The two points we have are (2,8) and (0,0). So, in this case,
= 2,
= 8,
= 0, and
= 0. Let's substitute those values into the formula and solve to get the slope:



So, the slope is 4.
