Step-by-step explanation:
Required
Arrange in increasing order of slope
Slope (m) is calculated using:
![m = \frac{y_2 -y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-y_1%7D%7Bx_2%20-%20x_1%7D)
So, we have:
(a) (15, 30) and (20, 40)
![m = \frac{40 -30}{20- 15}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B40%20-30%7D%7B20-%2015%7D)
![m = \frac{10}{5}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B10%7D%7B5%7D)
![m =2.00](https://tex.z-dn.net/?f=m%20%3D2.00)
(b) (12, 32) and (18, 48)
![m = \frac{48 -32}{18- 12}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B48%20-32%7D%7B18-%2012%7D)
![m = \frac{16}{6}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B16%7D%7B6%7D)
![m = 2.67](https://tex.z-dn.net/?f=m%20%3D%202.67)
(c) (27, 12) and (72, 32)
![m = \frac{32-12}{72- 27}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B32-12%7D%7B72-%2027%7D)
![m = \frac{20}{45}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B20%7D%7B45%7D)
![m = 0.44](https://tex.z-dn.net/?f=m%20%3D%200.44)
(d) (45, 15) and (60, 20)
![m = \frac{20-15}{60- 45}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B20-15%7D%7B60-%2045%7D)
![m = \frac{5}{15}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B5%7D%7B15%7D)
![m = 0.33](https://tex.z-dn.net/?f=m%20%3D%200.33)
(e) (27, 2) and (243, 18)
![m = \frac{18-2}{243- 27}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B18-2%7D%7B243-%2027%7D)
![m = \frac{16}{216}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B16%7D%7B216%7D)
![m = 0.07](https://tex.z-dn.net/?f=m%20%3D%200.07)
(f) (18, 63) and (24, 84)
![m = \frac{84-63}{24- 18}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B84-63%7D%7B24-%2018%7D)
![m = \frac{21}{6}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B21%7D%7B6%7D)
![m = 3.50](https://tex.z-dn.net/?f=m%20%3D%203.50)
(g) (63, 9) and (84, 12)
![m = \frac{12 -9}{84- 63}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B12%20-9%7D%7B84-%2063%7D)
![m = \frac{3}{21}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B3%7D%7B21%7D)
![m = 0.14](https://tex.z-dn.net/?f=m%20%3D%200.14)
From least to greatest slope, the pair of points are:
(e) (27, 2) and (243, 18)
(g) (63, 9) and (84, 12)
(d) (45, 15) and (60, 20)
(c) (27, 12) and (72, 32)
(a) (15, 30) and (20, 40)
(b) (12, 32) and (18, 48)
(f) (18, 63) and (24, 84)
