Answer:
center=(-7,5)
Step-by-step explanation:
The center form of the circle equation is in the format (x – h)^2 + (y – k)^2 = r^2, with the center being at the point (h, k).
you can find center by making equal to zero each term, then:
x+7 = 0
x=-7
y-5 = 0
y=5
then the center is (-7,5).

Answer:
y = -3/2x + 11
Step-by-step explanation:
2x - 3y = 21 => 3y = 2x - 21 => y = 2/3x - 7
Perpendicular lines have slopes that are negative reciprocals of one another
so slope of perpendicular line is -3/2
y = mx + b
y = -3/2x + b
Using (2,8)
8 = -3/2(2) + b
8 = -3 + b
b = 11
y = -3/2x + 11
Answer:
-2x
