Please find the complete question in the attached file.
In the given image file when we rotate it to 90 degrees clockwise so the value as the rule is 
Putting the value in x = 5 and y = 4 then:

Answer:
35.33
Step-by-step explanation:
The circle with radius 5 has a sector with a central angle of 9/10 pi.
The area of a sector is given as:

where α = central angle of the sector in radians
r = radius of the circle
The area of the sector is therefore:

The area of the sector is 35.33.
Answer:
Please see attached
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals to each other, that is, if one slope is a/b, the other is -b/a
in this case, the given slope is 1/3, so the other line's slope is -3/1, which is -3
from the graph we see that the y intercept of line b is -4, so the equation of line b is: y=-3x-4
