use similar right triangles to develop an understanding that slope, m, given as the rate comparing the change in y-values to the change in x-values, (y2 - y1)/ (x2 - x1), is the same for any two points (x1, y1) and (x2, y2) on the same line

Q.
Carrie says that because triangles DEF and ABC are similar right triangles, the slope of AC and the slope of DF are equal. Robert says that the slope of AC and the slope of DF cannot be determined because they are congruent. Who is correct and why?

Q.
Steven says that the hypotenuse of the triangle PTA will have the same slope as the hypotenuse of the triangle RID because they lie on the same line. Julissa says that the slope of RD will be opposite of the slope PA because the triangles are not similar. Who is correct and why?
