(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)
Step-by-step explanation:
Required
Arrange in increasing order of slope
Slope (m) is calculated using:
So, we have:
(a) (15, 30) and (20, 40)
(b) (12, 32) and (18, 48)
(c) (27, 12) and (72, 32)
(d) (45, 15) and (60, 20)
(e) (27, 2) and (243, 18)
(f) (18, 63) and (24, 84)
(g) (63, 9) and (84, 12)
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)
