Which equation represents a circle that contains the point (-5, -3) and has a center at (-2, 1)?
distance formula: v(x2 – xy)2 + (v2 - yp)?

(x - 1)2 + (y + 2)2 = 25
(x + 2)2 + (y – 1)2 = 5
(x + 2)2 + (y – 1)2 = 25
(x - 1)2 + (y + 2)2 = 5

An object is accelerating at a constant rate. its velocity in feet per second as a function of time in seconds can be modeled by the linear function v(t) = 2.5t. what does the dependent variable represent for this function? a) acceleration b) distance c) slope d) velocity
