• The slope of line HK is less than the slope of line PK, because the ratio of the change in y-values of the endpoints to then change in x-values of the endpoints is less for line HK than it is for line PK.

• The slope of line HK is equal to the slope of line PK, because the ratio of the change in y-values of the endpoints to then change in x-values of the endpoints is the same for line HK as it is for line PK.

• The slope of line HK is greater than the slope of line PK, because the ratio of the change in y-values of the endpoints to then change in x-values of the endpoints is greater for line HK than it is for line PK.

• The relationship between the slope of line HK and the slope of line PK cannot be determined, because the triangles are congruent.
