What is the equation, in point-slope form, for a line that goes through (8, −4) and has a slope of − 5 6 ? y+4=− 5 6 (x+8) y+4=− 5 6 (x−8) y−4=− 5 6 (x+8) y−4=− 5 6 (x−8)

Is trapezoid abdc the result of a dilation of trapezoid mnpq by a scale factor of ? why or why not? yes, because ab and cd are each the lengths mn and qp. yes, because sides ab and cd are parallel to sides mn and qp. no, because ab is the length mn but cd is the length qp. no, because sides ab and cd have different slopes from sides mn and qp.

In the polynomial below, what number should replace the question mark to produce a difference of squares? x2 + ? x - 36

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.
