I need help on 1-7 some one please help me work it out

Triangle abc and triangle deg are similar right triangles. which proportion can be used to show that the slope of ac is equal to the slope of dg? a) 4 − (−7) 0 − 4 = −1 − 10 4 − 8 b) −4 − (−7) 0 − 4 = 4 − 8 −1 − (−10) c) 0 − 4 −4 − (−7) = −1 − (−10) −4 − 8 d) 0 − 4 −4 − (−7) = −4 − 8 −1 − (−10)
