Definition: Usually represented by the letter r, this gives the linearity of the relationship between two variables, often in a scatterplot. The value of r ranges from 1 to 1, with -1 meaning perfect linearity and
negative slope, 1 meaning perfect linearity and positive slope, and 0 meaning no linearity. It is called the
coefficient

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.

Describe a situation that you could represent with the inequality x< 17
