Triangle abc and triangle cde are similar right triangles. which proportion can be used to show that the slope of ac is equal to the slope of ce? a) 0 − 2 / 3 − 0 = 2 − 4 / 6 − 3 b) 2 − 0 / 3 − 0 = 4 − 2 / 6 − 3 c) 2 − 0 / 3 − 0 = 4 − 2 / 3 − 6 d) 2 − 0 / 0 − 3 = 4 − 2 / 6 − 3

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
