Determine what rule the function machine is using

Choose the equation below that represents the line that passes through the point (2, 4) and has a slope of 3. a) y − 4 = 3(x − 2) b) y − 2 = 3(x − 4) c) y + 4 = 3(x + 2) d) y + 2 = 3(x + 4)

Factor the polynomial. b^2 + 4b + 4

Use the distance formula to find the distance between (-3,5) and (3,1)
