Which statement is true regarding the slope of AC and CE?
The slope of AC is LESS THAN the slope of CE because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is LESS for AC than for CE.
The slope of AC is GREATER THAN the slope of CE because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is GREATER for AC than for CE.
The slope of AC is EQUAL THAN the slope of CE because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is EQUAL for AC than for CE.
The relationship between the slope of AC and the slope of CE cannot be determined because the triangles are congruent.
