Which is the equation of the line that passes through the points (-4, 8) and (1, 3)?

Step-by-step explanation:

(3 - 8)/(1 + 4)= -5/5= -1

y - 8 = -(x + 4)

y - 8 = -x - 4

y = -x + 4

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
