1. Move the points so that the slope of the line is negative. What direction is the line going?[br][br]2. Move the points so the that slope of the line is zero.[br] a. What direction is the line going?[br] b. What is the equation of the line drawn?[br][br]3. Find two lines that have the same slope. What two points did you use to form each line?
