3.What is the equation of a circle with a center located at (4, -1) and a radius of 9 a. (x + 4)2 + (y - 1)2 = 9
b. (x + 4)2 + (y - 1)2 = 81
c. (x - 4)2 + (y + 1)2 = 9
d. (x - 4)2 + (y + 1)2 = 81

8 2/3 is the answer

step-by-step explanation: just use a calculator

did you get the answer yet?

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
