The circle below is centered at the point (2.-1) and has a radius of length 3.
what is its equation?
a. (x+1)2 + (y-2)2 = 9
b. (x-2)2 + (x + 1)2 =
32
c. (x-1)2 + (y + 2)2 = 9
d. (x + 2)2 + (x-1)2 =

the monthly balance will be $75,000

there is no grid

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
