Which polar coordinates represent the point plotted on the graph? select all that apply. (2 answers) a. (-4, 90 degrees) b. (4, 90 degrees) c. (4, -90 degrees) d. (-4, 270 degrees) e. (-4, -270 degrees)

1. A

2. B, D

3. A, D, E

4. C

5. A

Step-by-step explanation:

The correct options are (b) and (d).

Explanation:

It the polar form , where

The polar coordinate are in the form of .

From the given figure it is noticed that the value of r is 4 and or .

So the point is defined as and option b is correct.

The value,

Check the each option if we get the same value then that option is correct.

For option a.

Therefore option (a) is incorrect.

For option c.

Therefore option (c) is incorrect.

For option d.

Therefore option (d) is correct.

For option (e).

Therefore option (e) is incorrect.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
