We are asked to find the slopes of the given points and arrange them in increasing order.

Recall that the slope is given by


m=(y_2-y_1)/(x_2-x_1)

Let us first find the slopes of the given points.

1. (15, 30) and (20, 40)


m_1=(40-30)/(20-15)=(10)/(5)=2

2. (12, 32) and (18, 48)


m_2=(48-32)/(18-12)=(16)/(6)=(8)/(3)=2.67

3. (27, 12) and (72, 32)


m_3=(32-12)/(72-27)=(20)/(45)=(4)/(9)=0.44

4. (45, 15) and (60, 20)


m_4=(20-15)/(60-45)=(5)/(15)=(1)/(3)=0.33

5. (27, 2) and (243, 18)


m_5=(18-2)/(243-27)=(16)/(216)=(2)/(27)=0.07

6. (18, 63) and (24. 84)


m_6=(84-63)/(24-18)=(21)/(6)=(7)/(2)=3.5

7. (63, 9) and (84, 12)


m_7=(12-9)/(84-63)=(3)/(21)=(1)/(7)=0.14

Finally, let us arrange the slopes in increasing order (from least to greatest)


\begin{gathered} m_5=0.07 \\ m_7=0.14 \\ m_4=0.33 \\ m_3=0.44 \\ m_1=2 \\ m_2=2.67 \\ m_6=3.5 \end{gathered}

Therefore, the increasing order of the slopes is

m5 = 0.07 (27, 2) and (243, 18)

m7 = 0.14 (63, 9) and (84, 12)

m4 = 0.33 (45, 15) and (60, 20)

m3 = 0.44 (27, 12) and (72, 32)

m1 = 2 (15, 30) and (20, 40)

m2 = 2.67 (12, 32) and (18, 48)

m6 = 3.5 (18, 63) and (24. 84)
