Step-by-step explanation:
1) m∠1 = m∠4, m∠2 = m∠3 (1) Given
2) m∠AFC = ∠1 + ∠2 (2) Angle Addition Postulate
3) m∠EFC = ∠3 + ∠4 (3) Angle Addition Postulate
4) m∠EFC = ∠1 + ∠2 (4) Substitution
5) m∠AFC = m∠EFC (5) Transitive Property

Answer:
slope of r = -9/4
slope of Q = 4/9
Step-by-step explanation:
x1 y1 x2 y2
10 6 1 2
(Y2-Y1) (2)-(6)= -4 ΔY -4
(X2-X1) (1)-(10)= -9 ΔX -9
slope= 4/9
