Write an equation for the number of boxes, b, that were sold if m dollars were collected.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
